It is 3.425 for the H22. I would imagine it would be slightly larger considering the increased displacement from 2157cc to 2259cc in the H23. Let me see if I can track it down.....

you can swap an h22a vtec head to an h23a. think i heard something about the h23a not moving enough oil with the stock pump or something, gotta get the h22a's. 
maybe somebody else knows what i'm talking about. but i know the heads swap!!!

the vtec head needs to have one or two more oil squirters that the H23 block does not have, which means you have to fabricate your own.
it often leaks oil if not done right.
if your engine H23 is not in very good condition, the head and block will not line up.
IMHO, i think its easier and more efficient to swap in the H22...unless you have the money to do it right
DAMN your compression is 10.1:1 with all that boost? Know wonder you make so much HP! So approx how much $$$ do you have tied up in your ride? If you don't mind telling.
