I am tired of people saying how its not possible and how it is not worth the money and blah blah blah. well, guess what, it is possible and it is worth the money, especially if you are going from the f22a1 or f22b2. this DIY is from WikkedV16 from CB7Tuner.com - 4th Generation Accord Online Community, the thread is here: CB7Tuner Forums - DIY request on H23 head swap this is for the F22Ax block with an h23 head. Now, it is pretty much the same for F22B2's. I'm not sure about F22B1 since it has vtec, but im pretty sure it WILL swap on. If you fuck anything up, thats you're own fault, dont come complaining to me or Wikked.
