Re: piston/block heigth
I agree with MikeK,. I have run engines that had out of the box pistons and NO Counterbore on the head and never had a problem. This means the head was absolutely flat and it never hada piston hit, even in a racing situation. You could surface the stock head 125 thousands and never have a properly fitted piston hit it. Even a high compression head shaved to flat won't hit the pistons. Yours is wrong with one piston protruding .080 and the rest at less. Sounds like a hack job on the crank.
