howdy y'all, I have this random DOHC head I got from a friend who was cleaning house, and he said it was a b16 head, but now I'm beginning to question that.

what do you think this if from?

 

what does it say by the exhaust ports?does it say p30 by the vtec sol?

 

I'd say it's P74 head given that there's a stud in the middle of the head for the valve cover. B-series VTEC heads don't have that. Not to mention the camshaft saddles are too thin to be a VTEC head. VTEC solenoid mating surface is also non-present.

The upper radiator housing exit on the front of the head also indicates a P74 head....definitely not PR3 (B16) b/c the upper radiator housing exit is on the back of that side of the head.

 

im blind, thats not even a vtec head...the front will tell you

 

think it could be a pr4? I'll check the code in the morning for certainty.
