I need to know since I have a F22B DOHC motor in my Prelude, what kind of performance parts can go on my motor? I mean, I know I can put performance parts on it but I need to know what parts are compatible with my motor that are used on other F and H series motors that are DOHC. I heard that H23 parts are the same as the F22B DOHC parts but wasn't sure.

 

It's an H23 head.

 

So all the Performance parts I get will have to be of an H23?

 

right , the f22b head is essentially a h23 head. the ports and bolt paterns are all the same. I belive the valaves and cams too are the same.

 

Ah ****, thanx man, I been puzzled for weeks and askin around but never got a real answer. ANd thanx again, I really owe ya!!!

 

The head is different becuase of the 85mm bore. h23 has an 87mm bore, but they are basically the same. I was using a dc h23 header on my f22b.
