p72 head with p73 intake mani.

Alright so i came accross a gsr head. Has a itr valve train, JG cams and cam gears. But The intake manifold on the head is a type r. My understanding was that a itr Intake manifold Would not fit on to the p72 head. I have pictures to prove and i drove the car this head came off of and it ran fine like this. How is this possible if they are not compatible? thanks for any help, and sorry if this topic has been beatin in to the ground.

Can’t help you but I would like to see the pictures at least.

its called BLOX or SKUNK 2

A p72 is from a B18c1 head and the P73 intake is a ITR…so there not oem campatible. Unless, the aftermarket company made a ITR replica to fit a P72 head.

its called BLOX or SKUNK 2…

No, its called Type r intake manifold on a gsr head. That’s what the threads about. I would no if it was either of those two.
If you would like pics i can supply them tommorow.

if its a p73 im on a p72 head, the im flange has been re-drilled to fit the p72 im mounting location.
