The Mopar heads are already mildly ported (P4876257) and good for
about a 25 h.p. increase. I have used the Extrude Hone process on cast
headpipes for the jet-skis that I race and have had excellent results.
I have heard everything from good to marginal on improvements for
automotive heads. I would personally go with a set of Dick Landy
ported heads. I think you would be more than satisfied with their
work. Call: 818-341-4143
