Sorry about that! I was using the iPad, and couldn't find the proper symbols. Once you do it a few times, you can do it on a calculator in less than 30 seconds.
So, if you have a flat top KB, probably the 237 piston , and zero deck, you'd be 10.32 to 1 with 84cc heads, and 10.92 with the 78cc TF heads. That's assuming you have a composite head gasket at .039 thick, which most are.
Also, never assume the advertised CC's of products. You'll find they are all over the board.
