For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.


Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

    H series head on f22a1 block= Need Help

    I have been researching this and havn't found out much of anything. I know it can be done, because ive some cars with it done. my problem is no one is saying what it took to do it. I have a complete f22a, i want to put a h22a head on it, but ive heard the h23 is easier. I would like to know which is better. Im thinking the h22 would be harder but it doesn't matter. If it can be done and put more power down than the h23 then ill get it done. I need to know exactly what parts to get and what hole to block off to make this work. If anyone has done this or knows a site that has a step by step of this let me know, thanks. Aslo after its built , its going to be turbo, so if one head is better for turbo i would like to know.

      . . . the h22 head is superior in pretty much every way possible . . . talk to shadetreecustoms, hes done the head swap onto his f22ax

          i dont think anyones dynoed an f with an h head swap . . . id assume the real H would produce more power . . . but you never know.

            The real H would definitely make more power. If you put the H head on as is w/no internal work you're gonna lose compression, and if you rev it up to 7400 rpm you're gonna spin a bearing.

            If you wanna make H22-ish power, or at least run H22-ish numbers, here's what you should do: get an H23 head & some Crower street cams, and find a good shop to weld some aluminum on the area around the valves...that'll give you some more compression, maybe bump it up to 9.5:1 or so, and seal the 2mm extra bore on the head. Just slapping an 87mm head on an 85mm block will be disappointing at best.
