lifter/valve lash question
I just want to verify valve lash with the lifters I am using. I am using CCA-850-16 which are comp cam oem replacement lifters. I have them valve lash set ¼ turn past zero. The reason I ask is because I noticed the thread about Comp R’s being set at zero. Mine are obviously not R’s, but anyone know exactly what spec range?

If you want to know the exact setting, ask comp cams about the rockers you have. It's measured in thousandths of an inch telling you how far the lifter plunger should get depressed. Then find the thread pitch of your rocker studs and calculate the distance between threads. That is how far the nut (polylock) will go down with one full turn. So then you know exactly how far to turn the nut past zero lash.
I think it's called "lifter preload" or something like that.
