Head Porting Recomendation?

What is OOTB?

I'm a bit confused when you say they outflow the Victors to .500 but haven't raced them against the Victors? You mean at a dragstrip? I mean if they outflow them below .500 it would seem a lower RPm street engine or a lower RPm engine in general with a cam that is under .600 lift would thrive with the perf RPms.

I mean Out Of The Box (unported). If I was going to run a cam .500" lift or less and not port my cylinder heads, I would choose the RPM heads. If I already owned RPM heads and my horsepower goals were 750 or less, I would have my RPM heads ported. If I had to buy cylinder heads because I had none and my horsepower goals were 600 or more I would by something other than RPM heads. Something like Victors, Indy EZ or 440-1.

No OOTB aluminum head will support 750 horsepower unless it comes out of the box ported.

Any aftermarket aluminum cylinder for big block Mopars can be ported to 750 HP. ANY of 'em.
