I have built me b series but not a h. Im just asking if i can just bolt the h22 head to the h23 block? Dont worry about if i am mechanically inclined enough to do it. If it sounded like i was asking if it is a bolt-on swap into me civic thats not what i was asking. I know what is needed for a swap. I had a feeling that it may be like the ls/vtec setup for the b series. (dowel pin, oil line)
