I currently have the MMS stage IIx(11.2cr) heads on my car which are 4.8 heads. I am thinking of building a 6.0 iron block motor this winter. Will these heads work well on the 4.0 bore or do I need to get some different heads? I a guessing that I need to put in some 2.08 valves to feed the big motor.
