Don't W2 heads flow more than that? I know those are BB - just saying should a BB require some serious flow?



You can get 300cfm out of a W-2 with some heavy port work. Once these are leaned on, theyll probably approach 330.. Also, these are true stock replacement heads so you cant expect race like numbers..
