Hi everyone, I have a Honda cylinder head w/o cams but I can't tell whether it is a geniune JDM Type R head or not.

This is what I found:
- It has all the Type R valvetrain, springs, retainers.
- It has DC2 ITR/EK9 CTR Valves, LMAs.
- It has a Type R 3 angle valve job which is Type R specs.

However, a few of my m8s have disputed that it is not a Type R head but the peeps which I bought the head off insists that it is a Type R head.

Can anyone shed some info in interpreting the codes found on the wall of the head that connects to the exhaust manifold side?

On the right side, there is PR3-1 stamped, on the left, there is 4 circles with a | dividing some numbers. From my understanding, the 1st from left indicates the year of manufacture, the 2nd indictates month? (not sure), 3rd indicates day? (not sure), and the last one is the important bit that indicates the head code. I don't know what code is it for a JDM Type R head?

All assistance to solve this is much appreciated.

I do not have any photographs of the head unfortunately.

Thank you very much.

Ben

 

B16/B18C(5) [non-GSR] heads are stamped PR3-x (where x = 1,2,3,4). If it has all the stuff you say, then it is a Type-R head minus the cams.
