5.3 Head Install and Torque Spec/Sequence 

Yes

@@jorge56188 I’ll be purchasing another LS soon and will be doing a complete video series over the entire build no matter how small the detail I’ll make sure I put all the info in the next video.

That’s exactly what I came for

@@seananthames7017 first pass they are 22 ft lb second pass 90° third pass 50°

No idea, haven't messed with a Gen 5 yet.

Everything is in the description.

With the TTY bolts yes. You can buy ARP bolts that are just a torque spec only.

9 and 10 what is the final torque pound?

And have the same bolts

You have to purchase one specifically for angles not all torque wrenches have it.

I bought a Durofix 1/2" ANGLE digital torque adapter. $85 on Ebay. For use with existing 1/2" breaker bar. Just doing one 2003 LS engine. Positive reviews. Maybe upgrade if I get totally bitten by the LS bug. 1982 Volvo LS swap. Thanks for the well done Video.

Good looking out.

No torque specs are a little different.

@3rdGenC10s where can I get the 2009 spec I'm having a hard time finding them

This is all o could find for a Gen 5 www.silveradosierra.com/threads/2016-sierra-5-3l-head-torque.731535/

2003

No, they end at 50 degrees.

I understand that both nine and 10 is 50° final pass but what was the foot pound on them????

Don’t know wasn’t concerned with final torque. Just following the the proper steps.

Well, I appreciate you responding back, great video will definitely subscribe, I’m going to torque bolts 9-10 to 50lbs for final pass…. Going to send it

I have the tool to do it to GM spec instead of just “sending it”
