I think the gasket spec is suppose to be .030 with .002 on piston. My piston is .004 in hole and need to do some machine work, so I was trying to see what I had to make it work or not. I will keep rocket shop for a go to and get something closer to fit and do less machine cutting. Thanks again. Jeff

It's .002 down.Otherwise ,it would say .002 ab..
You need .032 total, minimum..About as tight as you want anyway.
Hmm, I think I see a phony factory spec.
How about an offset grind on the crank?
