Which head should i put on f22a1? H22 or H23

[theSOB]

I have an f22a1 and i'm looking to do a head swap but am not sure exactly what i want. Lately i've been leaning more towards the h23 head becuz my header will bolt right on and it sounds easier and better if i wanna boost it later. However, the h22 does offer vtec which is nice but i know i would have to plug up some holes and it would be higher compression for N/A. What do u guys prefer? And which ecu should i get? whats the overall best setup for a head swap?

Personally, I would either do a complete h22 or h23 swap rather than just doing a head swap.

Neither one will give you significant gains. The F22A head actually outflows both of the heads you're looking to replace it with if you do a little porting.

It's been done before, so there's no point in doing it for originality. The gains don't really justify the work, and the increased potential for reliability issues doesn't make it worthwhile in my opinion.

If you want an H series, swap in a full H series... or mod your F22A.

The f22a6 head would probably be the best bet if you really want to swap just the head.

The F22A6 probably makes as much power as the F22A block with an H23 head on it.

the reason i was going with just the head is because the f22 block is better than the h block (no frm and the f22 doesnt need to be sleeved). the difference is its only 85mm vs 87mm. so i was planning on gettin pistons and roda from h23 and boring to 87mm, puttin the head on and i got a h23, possibly better.

the f22 head flows better than either of them

[theSOB]

but does the better flow make up for the performance gain of dohc

yes it does! the f22ax head also has better valve angles!

it really all depends what your looking for, and what type of build your doing.

yes it does! the f22ax head also has better valve angles!

thus creating a better flowing head.

[theSOB]

so i should look for a6 head? or should i look for the sohc vtec?

[noobcake]

the f22b1/2 head is different than the f22a head, if that is what your talking about.
because obviously a D series head wont bolt up.

but if your going to use your f22 block, then use an F22a1/4/6 head.

You could do either head swap (h22/H23) and have to block off holes/passages, or IF you like you could try to track down a JDM F22B DOHC head.

The JDM DOHC F22B Head bolt EXACTLY up to the F22A block. This I know for a fact. Both headgaskets are identical. (Did this before I stuck my F22A1 head on my JDM F22B DOHC block.)

[deevergote]

SOHC VTEC heads flow TERRIBLY. The F22A head that you have now is the best option. All of the F22A heads are the same. Just the camshaft and valvesprings are different on the F22A6 head.

There is nothing wrong with FRM sleeves. People talk like it's a bad thing. FRM is lighter, stronger, and has better cooling properties than the F22's iron sleeves. Depending on what you plan on doing, you'll ALWAYS have to resleeve. If you want a turbo monster, the F22A sleeves aren't going to hold up any better than the H22's FRM sleeves. Mahle Gold Series pistons work just fine with the H22's FRM sleeves.

ok, so if i stick with my head, and switch out its internals, the next decision is the bottom end. i'd like to get pistons, rods, and possibly a crankshaft also. any ideas? i'm thinking wiseco just because some1 gave me a sticker a long time ago and its been on my car forever (ricer-ish i know). not a very good reason to choose internals, but i have little to no knowledge of pistons.
