I bought my car and have realized that it's all mix and match. I have found out what the block and trans are (99-00 civic si block) (S80 LSD trans CTR or ITR). I thought the head was a 99-00 si but I have bought 3 exhaust gaskets for a 99-00 si and it isnt a si head. The head is stamped PR3-2. I have seen that it might be a ITR or CTR head.... Does anyone know for sure 100% what that head is????

 

I might be crazy but I think the B16A/B and B18C's share the same exhaust manifold gasket.

All B series heads share the same exhaust manifold gaskets.

Also, the intake manifold gaskets are the same between all B16/CTR/ITR heads.

 

I might be getting the wrong part, who know gotta love autozone lol..... But what is the PR3-2 head?

 

I would guess si(b16) head, since you have a 99-00 civic si block.

Could be any B16/B17/CTR/ITR head. The stamp is purely which casting it came from, not what car it ended up on. There are 4 castings, PR3-(1-4), and any of these can be found on a B16 or ITR

 

Is there a way to tell what car it ended up in???

Does your cylinder head have any green paint on top, to left of the valve cover, around the cylinder #4 intake side (left side, closest to firewall when looking at engine from front of car)

Goofy description but hey it's late. ITRs have this green paint, but it can wear away, so it's not a sure thing.

 

Nope... no green paint..

 

You could see if the intake ports are ported/polished... but then again, it could just be a b16 stock head with an aftermarket port.

 

Well after a search of Advance auto parts computer I found out that the 97 Del Sol VTEC gasket was a dif. part number. I know that doesn't make sense because that engine and the 99-00 are basically the same. So I bought it and guess what... It fit like a glove.
