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.

I'm not going off that chart. I already pointed out that there is something I don't agree with on that chart in one of my earlier posts.

 

yup 97+ preludes USDM came with h22a4's
and there is no DOHC f22a motor
there was a Prelude S in the US however, it's what Honda sometimes refer to the base 5th gen model the S and well the SH for the ATTS model
