Ernie, A word on your compression ratio....Cylinder cranking pressure does not equal compression ratio. My cam last year had 285 lbs cranking pressure and 10.6 compression. My cam this year has 185 lbs cranking pressure with the same 10.6 compression. I didn't change anything but the cam. To get your compression ratio you need to know bore, stroke, head gasket compressed thickness, deck height, piston dish or pop-up and head cc's.
