How do I know if I have a pi or npi without disassembly? Is there a certain date/model change that lets you know?

96-98 came stock as NPI, 99+ are PI.

Is it a direct swap, just take the heads of a 99-04 with the internals and slap it in a 96-98. Do you need the intake too? Just asking cause I might do b4 summer if it is a direct bolt on that needs no modification, and can any person with minimal mechanics exp do it.

well lets put it this way .. it is alot of work

Dont forget that you can swap out the old intake manifold and cams n get pi ones for around 300-350, which should make around 35 rwhp, less work, cheaper, not bad for the price. Remember that there still is some custom work though.

Can you re-use 96-98 MAC lt headers with the PI heads?
