With the OP gasket thickness of .044" and the piston flat being .010" above the block deck like he says, the Eagle calculator shows 11.3 to 1 compression ratio.
That sounds correct. But because I have "issues" and I have most of the tools here at the shop, I stuck the piston out .050 and milled the dome down to get 11.08:1.
As of now, my quench is a bit loose, so if I run into detonation I'll pull the heads, use an .039 gasket and make it 11.25:1 and close the quench up a bit.
