nice program but I do not have a clue on what I should use for numbers on Gsk B(mm) and Gsk T (mm) when figuring compress? The CB calculator does not require these numbers.

As far as I know, these programs can only be used for the most basic of CR calculations. Any modifications to the heads, different valves or pistons send the calculations way off.
The only way I was ever taught was to clay the cylinder head combustion chamber and measure the displacement. With the advent of C&C heads, it's more accurate, but that only works with known heads and valves. Once a valve job is done, and the valves lapped into place, you have to do it again.
