Well I bought a head that is supposed to be a type R, but I really have my doubts. I bought it off the net and now I think I got ripped off. The stamp on it is PR3-3, and from what I've heard is that it's a plain old b16 head, I've read a bunch of other crap too. searching the forums didn't help either. anyone have any ideas??? I can take pics of it and post them, just tell me what part of the head to take a picture of and I'll do it, maybe I can find out what I really bought. Thanks

Well, the only thing I can tell you is that both b16 and b18c5 heads are PR3 heads. I'm sure the answer is in the second 3 though. If you've ever seen b16 cams it should be obvious whether the cams have bigger lobes. Also the valve springs should have the dual design to them(first gen b16's were the only ones with the single springs). And if you took a pic of the combustion chambers someone on here should be able to tell if they have a mild p&p as the type-r head does. Good luck man, down with scammers.Last edited by whiteyg2RS; 22 Jan 2003, 05:00:38.

pr3-3
i thought pr3-3 was the type r head, and pr3-4 is ab16..or maybe is pr3-2...i dunno, my b17 is a pr3-4 and almost positively sure that type r is pr3-3..ill let you know asap...double springs on intake and exhaust is a type r head...another way to know...hit you up later

Going by the PR3-x stamp will not tell you whether it's a B16A or B18C5 head, different ITR's will have different ending digits - same with the B16A. If you look at the cam holder that the distributor mounts to it should be painted green along with that corner of the head - that's one way to tell if it's a B18C5. Also, the indicators on the ends of the cams will tell you what car they're from.-Jason

Well, if any of the springs are single then you can tell it isn't a type-r head. So I guess the only way to really tell if it is a type-r head is to take it to someone who can tell the difference.<~~~
