supposedly its possible, sean hyland has done it, but i dont think that the heads actually flow much better (i think its like 7% better) so its probably not worth the money your dumpin into it. plus a custom set of cams will cost like 1500 alone. if you got the money and time, more power to ya!! id like to see how it was done and true power gains
Custom intake manifold is the biggest hurdle. Suppossedly there is a guy in Las Vegas doing one now. Just rumor from a little birdie. Couple of others under construction. Deep pockets needed.
