like i said before unless you have all of the parts laying around it would be much easier and probably cheaper to just do the whole swap. More than likly you will have the same amount of money in either or, but IMO the full engine swap would last longer than just a head swap and would have many less problems. But if you want information from someone who has already done the swap here is the link H22A head swap. Also read the whole thread not just the first post. There is alot more information in it.
