i dont trust that chart, there are several discrepancies on it, and i only looked at the listed H series motors.
97-98 Prelude did not come with a h22a1 for starters, h22a1 is my motor and was not produced after 96. there are other things too but i dont want to get into them to make my point.
my head is stamped p13, which is also my ecu code, my block is h22a1, so i would say the f22b head probably has its ECU code stamped on it. makes sense since the head and FI system are connected and thats the main harness connection to the ECU.
