How can you tell what engine an intake manifold came from. For example on a D16Z6 head it has a stamp P08 which indicates it came from that engine. Is there something like that for the intake manifolds?

 

I'd like to know aswell, I want to know if my d16z6 has a z6 or b7 intake manifold.

 

Same problem. I have a P08 HF-3 (d16z6 i think?) then also have a P10 IPT-5? they are pretty much the same, but a few small differences. Im getting more confused.

Wish there was like a list like you are asking for. There has to be one somewhere!
