Perhaps a better way to go is to duplicate the Fred Brewer head? They were getting 475-500 cfm flow ratings out them.

chevy prostocks are above 500, and have been for quite a while. you can put bigger valves in the big chevy head than a hemi head, w/o interference. if the vavles are kept they same size-hemi all the way.
