YES! the H23 head does fit on the F22ax block..

damn i dont like how the stock valve cover looks! its kinda looks like an ls.... but matbe i could do somthing to it

thats because the H23 is the LS of H motors.

if you dont like how it looks, use a H22 head instead.

[91-accord]

first note: in this thread i have copied/pasted everything i wrote in the f22b/f22ax thread.. this is in no particular order.. at the bottom ill do a final review of all my findings as to not confuse the fuck out of ppl.. with that said.. lets start hybridizinig?? lol our sohc's into dohc's..




sound familiar..?? well cb7deathride suggested that i start my own thread on the h22/3a/f22ax hybrid.. so as to not clutter the f22b/f22a hybrid.. thread.. a lil too late thou.. but what the hell.. here goes..

heres a picture of both h23 and f22 blocks



the differences are minimal.. im still researching for full proof.. i know its been done already.... with a different setup.. f22b2/h22a.. he had 2 plug 2 drain holes and that was it.. so well see what else i find

btw.. ud probably end up using a f23 headgasket to meet the bore's in the middle..

85mm of the f22a block and 87mm of the h23a head.. i believe if measured the head actual is like 86.5?? gotta look for that info again as well..
so the f23 headgasket would work just fine..

Why should I consider this setup? How much horse gain difference? In fact, I was actually thinking about this setup. Found an H23a head with intake manifold on Craigslist.com --> http://minneapolis.craigslist.org/pts/947521549.html what do you think? Is it worth the time???

[91-accord]

So, is it worth the swap? As far as time, labor, and satisfaction? Does anyone have any video clips of their f22-h23 swaps, f20a dohc, f22b, and or h23? Please.... I am very curious about the differences.

[91-accord]

So, anyways. I just picked an h23 for 150. The guy say that it had a head gasket leak.
