First off what is the combustion chamber size (CC) of the cast iron gt40p heads?

I'm building/rebuilding an engine for my 89 GT. I have a set of new gt40p heads I would like to use. The piston choise is the problem. I want to use forged pistons with floating pins and need to know the cc's for the compression ratio.

Thanks
