So I used the search and it yielded no results. Are there any options for our cars with PI heads swapped. I am reworking my exhaust and would like a set of kooks but am considering pi heads in the near future.

thanks

PI and NPI heads have the exact same exhaust port openings...

Intake ports are different between PI and NPI heads and yes the PI ports are bigger on the intake side.
