ITR/GSR is a B18C stamp
LS non-Vtec is B18B
B16, and B16A, B16A1, B16A2 are the only B16 codes I'm aware of, maybe I'm out of the loop?
After doing a quick google seach *which you should have done* it looks like its probably a B16A CTR head

ITR's aren't 1.6L so they wouldn't have a B16B head. B16B is a Civic Type R motor so you have a CTR head. As far as the difference between the two I honestly don't know maybe another member can answer that for you.

Since the B16B came around in 97, I'd say it's not a B16B head. The ITR came around in 96. So not an ITR head either.
The ITR/CTR/B16A share a head casting. There is a green stamping on the back of the CTR/ITR head.
The bare head is pretty much identical.

Re: Difference between B16A & B16B head (B serious)
the only difference between the pr-*1-4* B16B head and the pr-*1-4* B16A head is the cams are a little larger in the B16B,also has some minor port work done to them at the factory, and I THINK hallow intake valves to that save on weight
