Screw-in Rocker studs! Vortec Heads *Part #'s in description* 

Every Vortec head saved keep one of the 9 volt cars off the road...lol

Just a little note Eddlebrock makes a stud puller kit and all pieces in the kit could be purchased separately at one time. It contained a pulling block, taps and spot facing tool for the studs which used the screw in studs with the radius base and hex head for tightening the studs. Like you, I always used a washer with rocker balls and one of the rocker nuts. Helpful tip would be a little never seize on the stud and washer. Now days most aftermarket heads come with your choice of 3/8 or 7/16 rocker studs. And yes always use a sealer on the screw in studs. If you don’t you will regret not using it. What your doing is almost a lost art. Thank you for sharing.

As an old machinist I have to compliment you on the detailed explanation and clear video here. I would add one thing for those who don't know about taps. Use a four flute starting tap that is nitrate coated. The gold color tap is nitrate coating. A starting tap is tapered and will start much easier and tap straighter. I'll email you on the beehive springs soon.

When I drilled and tapped my camelbacks at home, I free-handed it. If your tools are sharp and you don't force it, you can eye ball it. You can't drill and tap willy nilly. When you do it its best to pull one stud at a time and finish it, that way you can use the other studs as a guide (no special tolls, just free hand). The stud hole has enough depth that even if you're the slightest bit off, it'll correct itself. Just can't force it. And take your time.

Amazing work! Thanks for making these videos👍

100% agree, very well done with great detail! ;)

Very nice knowing I don't have to pay a machine shop. Love the stock look also

Very informative and presented in a calm and educational manner. Keep up the good work mate.

Thank you for this video man, your technique is way more clear and easy that some of the oldest ones here in RU-vid!

Awesome video! Thank you!

Thank you! Awesome content!!! So much appreciated!

Good video I like your information good Thank You.

Way cool ! Thanks for the info

I didn’t realize these pulled out so easily. Thanks so much for the detailed instruction!

Great video. All your videos are very imformative. You speak well my friend.

I've been thinking about putting bigger studds in my 2.5 and 3.4 chevy V6 heads for some time, I've already installed LS springs on the 2.5 heads. no issues yet🤞. but once I get the high lift camshaft I will do the threaded studds. but I was planning on using 1/2" studds so I can install big block chevy roller rockers. ty for the demo. I can easily do that.

Nice vídeo! Very good! 🇧🇷

Great job 👍🏻🇦🇺

I did this once to a 305 L69 head and ended up cracking the bosses. I dont know if its a cheaper casting, or what, but I was cringing when you were tightening down the stud. Good Video!!!

great video dude thank you

Thanks great videshow!

I understood right away without having to go back once so yes, it's well explained ! Thanks

outstanding!

Thanks buddy, I’ve been hunting for a complete vortec stud how-to video, gonna pull my 906’s and and add studs and try some port work (first time) see what happens...I’ll check for cracks as per your request before I start any work lol 👍

Good video

Amazing vid, TY!

Great content, you need lots more subs.

EXCELLANT video ,

Great teaching, Can you do a vid on drilling oil return holes on vortec heads, i hear we need to drill holes so the oil drains proper.

Use anti-seize on the stud treads when pulling them. It will prevent the threads from galling.

Thank you verry helpful

Some studs have a raised roll and you can screw them down it contacts the head and tightens. They work great.

A side note. 4.3L vortec has metric screw in studs stock. You just need to buy ARP studs to run standard size roller rockers.

That's the way we do it , unh huh !😊

Thanks

"You're gonna need a good drill" pulls out ridged cordless 🤣

I use a stack of 5/16 washers that fit loosely on stud and keep backing off the nut and adding a washer or 2 until it pops out. About 20 washers

I plan on swapping to vortec heads on my 1990 silverado sport (350). Thr heads, Cam, springs, intake manifold and EFI. Hoping for 350-400 HP when done. Your content has been very informative. Enjoying it 👍

Good info, subbed.

side note if you are doing this with the heads on the block, be aware that some heads have the rocker arm studs going into the water jacket in the heads

Great content on your channel. Sub'd

I use my bearing for power steering pulley install tool

i ran pressed in studs witha dual coil valve spring. took 2 weeks before the studs pulled off on their own lol doing this now

I've never had a press stud pull out 20 years running 280 to 300 lb with used heads. Again agreed to disagree studs are a great update as you can use non self aligning rockers but from my experience I'd leave it to the machine shop cuz if you're not 90° square you will screw up the heads as I did in the past. Thank you

im about to build a set of 906s where did you get the studs. first time iv seen them style. im used to guide plate type studs

Don't get any Easter than that thanks brother

I'm just going to buy the BowTie Vortec heads--screw in studs come with them; thicker deck also...

The first stud I started to pull out I guess is the hardest one because that thing is in there I have a 2ft breaker bar on the nut trying to take the thing out

Can I use a set of self aligning roller rocker arms with this stud setup?

I've been following your channel for a while i need to replace valve seals on vortec head is there a set you like or recommend for a stock setup? and maybe a part number? 062 head thanks mike '

I'm interested in your vortec heads upgrade kit.

Great videos! I was hoping that you can help me I have a stock 400sbc and will installing 602 vortec heads on the motor is there a camshaft that you recommend the only thing I will be upgrading on the heads will be upgrading springs that come with the cam

Wish they made this tool for small block Ford heads. Seems like it would not be too hard to make

Thanks for all the info you put out on the Vortec stuff! I am happy to have found your channel! I know this is an older video so dont know if you'll see the comment now, but have a question that I can't find info on anywhere I look. I have a 98 C2500 pickup that is the heavy duty option (12,000 GVW) it has L31 engine code but has the RPO code for 4 bolt main engine. Had to do an intake gasket a few months ago and pulled the valve covers. My engine has what appear to be threaded rocker studs factory. Have you ever ran across this before? They have a hex where they contact the boss in the head. Dont know if it is because its a 4 bolt main Vortec or what, but I know its all OEM still. Have searched a lot online and never found any mention of this from anyone else.

I have a question I have a 1991 C1500 and I want to do a vortec head swap and lt4 hotcam with 1.6 roller rockers. What do I need to do to the heads to make them work with my combo? Thank you

sir have you even seen a SBC balancer seperate.. Im rebuilding a 4.3 chevy,, the sleeve on the balancer had a groove worn in it from the seal. I bought a speedy sleeve and put the balancer in the freezer for abt an hour to shrink the metal. I took it to my bench, installed the speedy sleeve and let the balancer come to room temp. I then took a rubber mallet and was getting the balancer started on the crankshaft. I noticed little pieces of rubber falling out, so I started hitting it with the mallet to take it off and the outer ring of the balancer seperated from the inner ring.,. so did me putting it in the freezer cause this? or was it just old and brittle.. the inner and outer parts of the ring seem to be glued together.. I was shocked that it seperated..

LOVE your videos! Wealth of knowledge. What is the part # for those screw in studs? Im excited to get started...lol

Question timing chain can I use a double roller timing chain in my l31 stock 880 block I know it came with a single roller I popped the cover open today while I’m working on the engine replacing parts just wanted to ask lmk thabks

Would you have to change your push rods? How would one know if to short. Great video currently doing a set of 416 casting 305 heads with these videos in mind

What about pinning the studs? Used to be a thing. Yeah it’s not as cool but it would be way cheaper and accomplish the same goal. I’ve never done it but I’m thinking about it for my upcoming stock vortec upgrade.

What year? I have a 1994 4.3L vortec I need a rocker "bolt" not a stud. Do you know where I can buy a stock rocker bolt???

Hi new to channel witch roller tip rockers you recommend ? Thanks

Have you ever had one of the screw in studs snap? 60 miles on a brand new 383 and I followed you advice in setting up LS springs on the heads but I went with a Z28 spring. I double and triple checked the retainer to stem seal clearance and I had about .050" with the proper installed heights. It was idling in the garage and I heard a loud pop and clatter and turned it off very quickly. I pulled the pass side valve cover and found a rocker stud broken and 2 bend push rods. I pulled the other valve cover and found one more slightly bent push rods. I pulled the heads and there is no valve to piston contact. So I pulled the heads apart and every inner spring was broken. This time I'm going to cut the guides down and use LS beehive springs with comp cam retainers. The lift on the cam is .504". All of the pushrods had wear marks where they pass through the heads, you mentioned enlarging the hole in the head for the push rods...how big should I go? Yes, I used all new parts including long slot self centering rockers and .050 offset keepers.

I've got a set of 1998 062 Vortec heads that just came back from the local Automotive Machine Shop after being Maga Fluxed and Decked. I was told to put OEM head bolts when I reassemble the engine...My question is do I buy new OEM Head bolts for the 1998 Vortec heads...or OEM head bolts for the 1982 Chevy 350 engine the heads are going on ...or is there any difference ? I would imagine OEM bolts for the 1982 350 block the heads are going on to !

I may have missed it, but where do you get this type of screw in Studs?

Thanks for the great how to vid , just a question though , what brand and part# are the rocker studs you are using ? Ive have some ARP studs but need the stud bosses machined down to use them , using these will be a much cheaper alternative . Thanks again 👍👍

How do I email you on vortec performance stud kit to modify the head I'm also intrested in you beehive spring kit. I'm doing your vortech head swap on my 94 5.7L I'm different on budget been building on the truck for awhile . Thank you for the video they are very helpful and easy to follow.

How far do you cut down your valve guides? I have been leaving a about 3/4 of the coil spring wire thickness for a small ledge so the bottom of the springs can't walk around & possibly contact my new seals.

Cky ftw

Will my stock rockers and hardware work with these studs I'm building a 350 with vortec heads with a comp extreme energy 268 I've been told it will be fine with the press in studs and I've been told to change to screw in studs

Hey, whats the part # for the actual new screw in stud ? Im sure it the correct height i need to order . Thanks for all your videos Bruhda. Im doing this as soon as i find the correct studs....Thank you

Cool video what studs are those

hi, do u have experience much spring pressure (open pressure) pinned studs can take? i have 416 305 heads which will be mildly ported soon..i would like to put screw in studs, but i fear of breaking the stud bosses when removing the studs..i have been thinking that pinning could be a bit more safe way as here in Finland, used SBC heads are unobtanium if i destroy the bosses and need to buy new heads. im going to put comp xe262 cam and 981 springs, and i believe press in studs cant take the the spring pressure if i rev the poor 305 sometimes to 5500

Great video. I have a problem though. I cracked an 062 head, bought a new one from OELINE, installed it. It ran fine for about 30 miles and up until I got it to 65mph. Then it started running rough. My mechanic said that one of my studs had started working it way out. He put locktite on it and screwed it down. Then when running he noticed it wobbling. Says I need another head. Why would this happen? Manufacturer responsible?

Have you ever had any of the stud boss break as you pulled out the studs? This is the biggest thing I'm worried about with this project is having to scrap the heads

Do you see a reason the pioneer # 850013 stud won't work? They have the hex shoulder on then to tighten it down.

Have you used the proform stud remover tool? Its about half the price. Im cheap but i seem to always regret saving a few bucks just wondering if it would be good for a single use

What about machining the stud boss? Some studs have a built in nut as part of the screw in stud

I’ve got set of 906 heads. Is there preferred screw in stud you use? I noticed the ones in this video didn’t have the shoulder on the. Is there a difference? Thanks

Anyone know the part # for these studs?

Whats the part number for the studs? You had said they were pioneer brand ?

Wanting to put the same studs in my 062’s are the new studs the same height or close enough as the old ones once installed?

Tell me you're going to dino this engine cuz I am curious about the numbers? you did a fantastic job I just know that one buy comp cams the Extreme energy is really close to the cam that you chose and it comes with springs and everything or at least text me back and let me know if that comes as a kit the springs and the cam? PS appreciate the help on the study extraction..& you can Teach an old dog new tricks ha lol

Worth mentioning there is 3 types of taps. Works pretty good if you start with a starting tap then move to a bottom tap or plug tap. Bottom tap having the least amount of tapere. And not sure on truth but a machinist told me to clean the tap and cast with brake clean and tap without oil. Cast will chip away dry and oil makes it plug up the tap

If the threaded studs look just like the stock press in, whats an easy way to identify if its already been done?

What rocker arms do you recommend for vortec heads with around a 530 lift roller cam?

Question what size double ended rocker bolts did you use here, only info I couldnt find throughout the video 3/8 to 7/16? Or???

Have you ever run LS valves on a vortec head using the valve guide liners? Ls valves are smaller diameter, think it would be worth much additional flow?

Hi rpm will pull them out regardless of spring pressure

Do you have a good budget self aligning full roller or roller tip rocker arm set you recommend that will fit vortec heads ? I want to stay in a 1.5 ratio (aftermarket cam), and want to use incognito type studs in 3/8 or even 7/16 incognito style without machining

I'm assuming that the process for pre-vortec center bolt heads is the same. What part number did you use for the studs?

Are the stock rockers self aligning?

Do you have a part number for the studs?

Do you have a part number for the studs?? Thanks for the videos!!

Do you have a set for sale that you have drilled?

The stud spacing on vortec heads is a bit different than the tools are made for

😓gotta take them back to the shop and spend more man we gotta talk this just tossed me to centerfield

Why did you not use studs that have the nut head built into the stud which bottoms out on the boss like ARP's? Because you can't use the tool for squaring the two studs up.

link to the parts?

I cracked some stud bosses at 25 ft.-lbs. of torque.
