I see Texas speed has the .40 gaskets and Thunder racing as the .45. I wonder if there are two gaskets or someone is wrong.

Im going with the 63cc, .40 gasket, with the TR224. I should be just under 11:1

calculated scr and dcr using an intake closing 73*ABDC, with a 62 cc chamber and a .040 cometic, i get 11.3:1 and 8.4:1 respectively. cometic carries a number of thicknesses, just thought .040 would be best. don't really need to twist above 6K with my setup. Thanks phil
