Direct, personally I agree, but only if the entire engine is aluminum. Since bolt on alloy stuff is more common these days than iron I wouldn't start bragging/showing it off until it was all mounted on an alloy block as well, you know, the whole 9 yards so to speak. THEN I'd let the Reynolds Wrap shine! Otherwise it's just another iron engine with alloy heads and intake....(insert sleepy face Gaemlin face here).
