Edelbrock RPM head owners unite!

I would think its all relative to what your building? A smaller motor like my low deck 426 responded well to the RPM heads being a 220 cc runner. more like a sbc head. lol made 525 hp and 552 tq very usable drivable motor with good street manors. I know trick flow makes killer heads for Fords, not real convinced about the mopar stuff yet.
