The lastest HPP did a comparison test on headers vs. ram air manifolds. I think that Heddman was the header that they tested. The test engines were a stock 398 and a built 455. There wasn't much difference on the stock mill. Might be something to consider. Plus one of the suppliers offers a ported manifold for those that want the sleeper look with a little pop.
