Just wondering if any of you would be able to help me on this. I have a cam that the specs are as follows: 234/241, 576/595 on a 111.8 LSA. I was wondering with that lift and 2.0/1.56 valves do you think that I would have piston to valve clearance problems if I milled the heads .020 with a .039 head gasket? I really want to get a bit more compression out of it, but I don't want to have to rebuild while I am at it. The pistons are stock type .040 over with valve reliefs. Please let me know if you have any insight. Thanks.

I don't think you'd have any piston-valve clearance probs. Anything below .650" lift is fine.
But let's have some more input on this for ya!

 

I dont think you will, but with .020" taken off the head you are probably getting close. I would mock it up with clay to find out before you go based on anyones word.
