        10.9 compression ? Are you sure about that ?
        What head gaskets ? I am running same kit with 65cc w2 heads and I calculate right around 10.9 IIRC ....
        one of us is wrong

        My heads have had significant milling. Prior to the milling the engine was 9.8 or 9.9 to 1 i believe. My engine builder did the calculations not me but I'd assume he's correct. He's been doing it for 35+ years and he's really good at it. Won the Mopar engine builder challenge and does many a professional drag race motors.

        It makes sense because he has dished pistons. My previous motor was very similar and ended up about 10.8:1 (20cc dish, 57cc heads, zero deck, 4 inch stroke, 4.040 bore, 0.039 gasket).
