I have a short block with undesirable 425NP dish pistons. I have measured and the pistons are .045 in the hole. The compression height of these pistons are 1.630. It seems the deck has not been milled. I would like to mill .020 off the deck and run a .020-.025 cosmetic head gasket. This would allow .045-.050 quench. Using a 66cc D0AE closed chamber head what would the static compression? I am shooting for 9.1:1-9.5:1 this extremely pump gas for friendly. Thanks in advance for your help.
