Those EP streetports aren't very civil either, considering, from what I've heard, they love their idle at 1300 rpms, which is almost bridgeport territory.
I just don't think a mild streetport (maybe 20-30% more port area) will flow enough for 200 whp. Maybe, maybe not.
Though, with an aftermarket intake manifold, you may be able to get 200 whp.
