F22B2 block. I want to put a ported and polished VTEC head on it that I bought at an extremely good price. I don't want to change to a H22 engine, at this point I don't see it as being worth the money. I am going turbo in about two months and from everything I have read the lower compression Accord engine is very good for it. At this point I am trying to do everything I can before that. Which brings us back full circle to the head swap and if I am going to have to change out to a F22B1 block or use my existing one.
