First of all, I am an amatuer mechanic so double check anything I say with a professional before you act on it. .. By my calculations, you need an additional 0.9889 cubic inches of volume above the piston to lower your compression ratio about 2 points. Raising your head by 0.0775 inch with a thicker head gasket and/or spacer would theoretically give you that additional volume. I don't know if there are gaskets/spacers available to do that, and I don't know what other problems thick gaskets might create. But that is the only simple solution I could imagine. Good luck.
