F22 SOHC or F22B DOHC??

I believe either will fit, but definately the F22B.

Well, no the F headers definately don't fit an H22.

****, I thought he was talking about an h22 head? my bad..

ummm, I thought the downpipes on the h23/f22 header was differnet? and is the placement of the o2 sensor on the f22 and h23 header different? I know on my h22 header, the o2 placement was on the very end of the downpipe, and on th f22 o2 placement is on the upper half of the header.

I know for a fact that the F22A and the H23 are the same. The F22B will not work with an h23 header. The exhaust ports are different.

The F22A exhaust ports look like this
0-0-0-0 With equal distance between them
The F22B exhaust ports look like this
0-00-0 With the 2 center ones being fairly close

The only reason I know is because Im trying to turbo my f22a and got the f22b manifold by accident and it didn't work but then I tried an h23 manifold and it worked.

correct!

f22a SOHC non-vtec and h23 DOHC are interchangable.

I think that people are confusing the f22b JDM DOHC with the f22b SOHC VTEC. The Jdm f22b will fit just not the f22b SOHC VTEC.

It's true.
F22B = JDM DOHC nonVTEC
F22B1 = USDM SOHC VTEC
