: The way you worded it didn't sound right. But I also never said you were wrong. Every technician has his own way of doing things. I do know that if you follow the factory GM manual to adjust the valves in their sequence the valves will be too tight. I basically was adding to do it in the order of the firing order. And if you think I am wrong about the spec zero lash simply ask the tech department at summit racing for the vlave lash specs on any small block chevy roller rockers. And that is what I have been trying to tell you.
I will have to agree with you there, everybody has their own way of doing it. And telling someone 0 lash can be confusing if they don't know exactly what to do. I wanted to make sure he knew exactly what to do. And as far as the tech dept.....They have to say 0 lash because their is 0 lash between the rocker tip and valve tip. But the thing they don't say is how you get it there. I am not saying you are wrong by telling him it was 0 lash, only trying to add to it and let him know that you have to tighten it further than just at 0. Not trying to cut anyone down, I just don't anyone who reads this to learn how others do things to get misguided. You can do it the way Kris indicated, which I have done, or the way I described which is the way I personally prefer. but just as Kris said, 1 full turn is to tight, so do not turn further than 3/4 and no less than 1/2 turn but do all the same.
