2. What you're looking for is piston to valve clearance. I set to vero lash and then back off 2-3 turns. If clearance is going to be a problem, you'll be able to see it then, before the valves actually contact the pistons. Even if turning by hand, you can damage a valve if the clearance isn't there.

3. The issue is with the hydraulic lifters. They're designed to collapse a little bit under use. When there's no oil pressure, they will collapse a lot more, and you'll never get full valve lift.

Thanks Bob, That's helpful to know.
The lifters I'm using are actually from another engine and are still full of oil so they will not colapse. Is that going to be a problem since as they are "pumped up" and will not collapse at all probably? Will that make adjusting the valve lash or rockers a problem using them on the cam and roller rocker install?
I think I read in my cam installation directions from Comp Cam that it was "not desirable" to use lifters filled with oil for the cam installation. Anyone know about that? I would really like to know before I use them if that is going to be a problem or not.
