    My experience is that the 5's run about a tenth better than the 4's. Everything should bolt on to both, except the header flanges are quite a bit different in height between the two.

    Stage IV heads.

    We run a 5.66 @ 256 MPH with Stage IV heads in an NHRA Alcohol Funny Car.

    I think I there is a little bit more in the combination.

    Not gonna run 5.40's though with them like the latest heads out there.

    Hope this helps
