Until someone fixes the crappy valve position which opens right into the cylinder wall they can throw all the port size they want at it. Somebody really needs to do a better head and so what if it requires different valve notches in your pistons--look at the success of the Kaase P51. J.Rob
Well yeah but these heads will probably be good for 750 hp on a pump gas 470 inch big block which is good enough for most of the bracket guys out there. Might not be the best design possible for a Mopar but they look like a very, very good bolt on type head.
