Edelbrock RPM heads CNC ported by Modern Cylinder heads will make that power no problem on a pump gas 500 inch motor Been there, done that I have made 625 Hp with a set of standard 440 port size 906 on a high compression bracket race 452 CI motor and a little more HP on race gas using a non ported set of B1-BS heads with standard 440 port size heads on another bracket 452 C.I.440 motor The block becomes the limiting factor when you start getting above 650 HP on the high deck Mopar blocks
