Matt - Here are some numbers from my spreadsheet assuming a 355, 64cc combustion chambers, 9.025" deck height (stock un-milled), and .038" head gasket.
Flat top pistons w/ -4cc total valve relief: 9.96:1 -12cc dished pistons: 9.16:1 So, you were right on the money guessing 10:1 w/ flat top pistons! For different gasket thicknesses and deck heights, each .010" changes compression by prox 0.2 points. For example, a thinner .028" gasket results in 10.2:1 compression, a thicker .048" gasket = 9.75:1. Have fun!
