I went to that site and the piston spec doesn't spell out the dome volume. It specs out the dome height which is not a lot of help because the height is not uniform. However, it does give cr when used with a wide range of cc heads and bore amounts. I would assume the cr given does include the standard 0.040" head gasket and piston recesses. So, that 30 over piston will give you 10.25:1 cr with a 76cc head, but that may be a little high for the cam you want to use. Can you find a piston with a little less cr using 76cc heads? 9.5 to 9.8 would be about perfect.
