706's are good heads. The Castech cast heads are the ones prone to crack. Just stay away from the ones with the battery looking symbol beneath the rocker stand. The ones Billy gave you are also Castech.
Yeah never let your Chevy drink the cool-aide. I’m so glad it isn’t a salad dressing maker. I always hate the gray foamy oil stuff. Nice video again. Don’t give up.
Typically it's best to use new lifter trays bud....hopefully the ones you have aren't sloppy which allows the lifters to walk on the lobes....don't ask me how I know this...fukn hell. lol
Yeah those are the beehive springs. You can always measure the spring pressure or find someone who can. Find the pressure needed per inch and compare it to your cam card. Shim them to the right height also. Funny I was thinking it’s looking pretty clean and you say it’s so dirty. Something about crap coming through the radiator at 80 mph makes dailies dirty. Weird.
