You have a PI intake that's for sure

I can't remember how to check the heads.

Go find a non-PI car and drive it! Then you'll know if yours has the PI heads.

the NPI intake manifold can have the aluminum crossover as well.

if you want to upgrade to the PI intake, I think Livernois sells a kit that comes with everything you need to install on a NPI engine, since its not exactly a direct swap.

i have a set of PI cams im selling if you are intrested.

easiest way i can tell if its PI intake or npi is look for that hole on the driver side of the manifold next to the plenum in the center. also if you have it off look at the ports. the intake ports on a pi are more rectangular and the npi heads are more of a circle.

Yea man I had the same problem with mine. I had just bought it and i didnt know whether it had the pi swap or not.. I raced another 98 gt and i smashed it but all i have is an intake and exhaust.
How did you find if yours was PI or not??
