thanks for the replies guys.
i really seriously considered the 4.0 head swap, but i heard that the only real hp numbers comes simply from the raise in compression it exhibits. that and i already have the header in the garage and im too lazy to send it back
as far as porting goes, i dont really have the cash for it. im sure it helps, but im watching the "cost vs hp" ratio. i dont wanna spend over $200(approx) on the head. can i spend money elsewhere that would benefit? like stiffer valve springs or roller rockers or something? just throwing some things out there..
