Repost from tech section, maybe someone here knows.
B18A/B18B non-Vtec valves are different from the respective Vtec valves.
B18C5 (ITR) valves have undercutting which is not on the B18C1 and B16A valves.
There may be other differences that are not popping into my head...I'm sure someone else will chime in.
