head swap

It is possible, and the x-flow head does flow better, but with several 
concessions/modifications. I'm going to do this on my turbo motor (x-flow on a 
3a block)

If you're going to run a x-flow head, you'll have to figure out a way to get 
your CIS injectors in there (which I don't even know if possible without a 
custom intake). This would also need the proper injector cups. ALternatively, 
if you're going to run EFI, that opens up a whole other set of mods. 

Also, the other concern is the main oil return galley in the head. In the x-
flow head, it's oval and in the JH (or any other 'traditional' 8v head) it's a 
cirlce. Some folks say they've been able to avoid oil leaks, but the 
recommended method is to have the head galley welded up into a circle.

You could always just get this one. Guy just lowered the price to $400:
