Glenn,
The safe way to go would be to have your head CCd -- checked for the volume
of each combustion chamber just to be sure that your figures will give you
the compression that you think you're getting (not to mention matching the
chamber volumes). Nothing like ending up with 11.5:1 compression b/c a PO
already bumped the compression -- or changed the head to a different version.
Once you have that information, you can do the math and figure out where you
are and determine how much to remove to get exactly the compression you want.
