World Pro Heads Oval Vs Rectangle

[ghittner]

Just finished my motor, a 454 stretched to 496, with a B&M 420 Megablower, dual 750's on top and all the good stuff inside. I'm running the World Merlin steel ovals because that's what I have and I've spent too much already. Would the rectangulars make more power at 12pds of boost or under? If so, how much? No dyno, I'm guessing approx 800-850 HP w/no intercooler. Am I close here?
