I have a friend with a 71 chevelle who is putting a solid roller 13-1 502 in it. It has the "roval" port aluminum GMPP heads. He wants a single plane dominator intake for it. Which intake will he need? rectangle...oval... I can't seem to find an oval for it*except maybe a 454O. He wants something like a super vic. I know there may be a good argument for an RPM airgap or simular, but He wants what he wants.

Dart oval and then match the ports.
