I just bought this ram manifold for my 289
the holleys are 450cfm's. what heads/cam do you guys think would work well with this manifold?? im going to be running 10.5 or 11 to 1's with an automatic and 4.11 gears in a 65 comet. I know stock ford heads do not flow good. Im looking to make around 400 hp if that is possible. Any info will help thank you
