You need to have the casting #'s on the head, and check it online. There are sites that have formulas posted to calculate the compression. It just takes research to find them.
I know that Clifford Performance shaves .060 off their performance heads, and recommends zero decking the block as well. Any reputable performance shop should be able to help.
Say goodbye to regular gas.
