to all concerned... oval port heads are only good for low HP application, on 454 ci and smaller, if you want to make power rect port is required... we are running in the water under load with throttles open and thats why a rect port head is required...

On 454 the oval ports will probably make more horsepower across the board.
Generally speaking, 540 and larger the rectangular ports have the edge.
Procharged? I think rect would be the ticket, but not much experience.
