Block Milling
If your pistons are .050" down in the hole, and you use a FP1008 gasket with .039" compressed thickness, then your quench distance would be nearly .080". That is not too good... in fact that is terrible. Everything I have read says you want your quench to be between .040" and .050" with the smaller number being better. I have heard some people are running as little as .025", but that is pretty risky. IMO, I would be trying to get some decent quench and not worry too much about the final compression ratio.
