Message Then you'll have to get the heads ported to match the now much larger intake runners. There was a picture on here somewhere of an extrude honed lower plenum on a stock head and the edge of the intake port on the head stuck out 1/8"-3/16" all the way around.

Anyway, you can get to 470hp, even at the wheels, without alot of extrude hone/porting/throttle body/intake piping work. None of that is going to hurt you really but if you're trying to spend money where it counts then it might be better spent elsewhere.
