... and don't forget that a not flat piston makes a big difference.

Billy, you need to add the volume of the hole in the (compressed) head
gasket as well as the volume of the cylinder above the rings to the volume
of the combustion chamber.  Then you add that total volume to the
displacement volume and divide the sum by the cc/unswept cyl/head gasket
volume to get the CR.  Unfortunately, I don't know what the gasket and
unswept volumes are.
