Guess The Compression Ratio

This is for flat top pistons Stan, I didnt know for sure if you had 5cc dome or dish pistons so I just decieded to do it with flat tops instead, let me know and I can redo in a second for you.

The KB107 piston is a flat top with 5cc reliefs so you should calculate it as though there is a 5 cc dish. Also, most head gaskets have a bigger bore than the bore of the cylinder those two factors would get you the same answer as the calculators that come up with 9.8
