Right now im making 12psi on stock heads, stock intake mani and a fully forged bottom end. At this point what will i benefit more from and aftermarket manifold or a set of ported heads. Im going to go with a set of stage 2 blower cams which ever route i go im just not sure what i will benefit more from. Any insight or advice would help me out cant afford both right now so its either or so none of that buy em both junk. Thanks guys

 

Ported Heads and blower cams. Stock intake manifold is pretty efficient and most people dont see major gains with replacing it with aftermarket ones.

you may not get very much from a new intake, but it's probably a good idea to replace it before it cracks.[&:]
