You mentioned 0.016 in the hole at the top, then I believe said 0.025 further down? If the block hasn't been decked this is more likely...

I cc'd a chamber on my 2nd set of 062 vortec heads and got 62cc's. Also I am in the hole .016". The .025" is the piston slap or piston to wall distance. I know that has little effect on the overall compression of the motor but just wanted to input all the data when jeepstrokers.com/calculator asked me for it. Also my pistons are H345ncp .030" with 4 valve relief (about 6cc's).
