Aluminum heads $ per HP?

Maybe we should have asked is this a street brawler or a quarter mile build? They are very different.
Better flowing heads might only be at there best at high rpm or at the strip.

Very true and build dependent. Though, so far, the have t had a ported head so larger in the runner and flow super high as not to show an improvement on any Sb I have built. I think I’d have to go to the extreme for that. Like a fully ported W-7-8-9? IDK

Engine master did a show on that with a SBF. While the largest head did t really loose power per sai, it did t do as well as the mid level head.
