First off as a pretense to this, Im a poor college kid, and ive already decided that for now im doing thumper ported E7s or GT40s and a letter cam, because I dont have the money for aluminums and a custom cam, and my money income isint enough so that I could save some for that, it would be gone before i could buy, so dont try to convince me otherwise. Now that thats out of the way, I saw that the B-303 has less lift than the stock cobra cam!!! why? so techincially I could run the B-cam on stock heads with 1.7rr's and not have to worry about piston to valve clearance and the like???
