the p haeds will drive you nuts... they take special exhaust manifolds or you can grind the crap out of a set of headers to make the plugs fit.

95-early97 heads are GT40s
later 97 and up are GT40P heads
the intake is similar to the GT40 intake but is setup to make more lowend then your typical GT40. the lowers are the same
you can use BBK shorty unequal lenght headers on the P heads.
when i cared about my other stang i had this same topend on it
ever tried that?

Sounds like the hassle is not worth the gains for these heads. I am thinking I would have been better of getting GT40 heads and not the GT40p.
The only hassle is with the headers... i purchased the FMS p headers and have them on my AFR heads now... if you dont have headers already its a perfect time to upgrade
