Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

    Enigne Head Swap Inquiry

    So, here lately, I've been wandering around local pick n'pulls, mostly to gather lips for ground effect, but i stumbled across something that made a nice little lightbulb go off in my head, that I hadn't quite started researching- I know that H22 and H23 heads fit on our F22 block, but what about F23 vtec SOHC heads?

    -Cuz, honestly, i dont want to do a DOHC swap. I wanna try and see what i can pull from a SOHC Vtec.

    -now, problem is, I also recently bought a 4-2-1 Exhaust head from Megan, of course, for the stock F22 Head. Would it fit, if I did decide to do any swaps? If so, I'll just say screw the swapping and set me aside an entire H22a.

    -Now, i looked and looked around in the beginner forums, and saw no content related to such an inquiry, and please, be gentle, for I am new to the honda community.

    The header will not fit. Also the head swap isnt worth it. Save for an H swap. Frank motors have been done, there are a few of them still around, but for the average joe its not something to get involved in.

      If you want to see what type of numbers you can get out of a single cam F-series then you've already got the best head on your engine now. The F23A could be beneficial if you used the block from the F23A and your current head with K20A2 pistons and a nice cam. This guy in San Antonio did and made great numbers. http://honda-tech.com/showthread.php...1#post46520723

        The SOHC VTEC heads flow like crap. You can make more power with your F22A head.

          Actually the F23 flows better at lower lifts and out flows the f22a on the exhaust quite abit.

            For the people that are too lazy or inexperienced (or both) to learn if it can even be done, let's just stick with the "lousy performance upgrade" argument.
            Anyone who knows enough to make power from a SOHC VTEC head will know enough to safely install it on an F22A block... or at least enough to get started.

            Plus, SOHC VTEC engines are dirt cheap. Why go through the hassle of a headswap when the entire engine can be dropped in. The entire engine swap presents much less of a reliability issue.

              the only thing id swap would be a jdm f22b dohc. i had a h23 head swap and while i gained a little bit of power through my butt dyno, it constantly smoked even after having the valve stem seals replaced and head surfaced
