I couldnt find exactly what I needed in the search so Im asking here. I have a 00' xj 4.0 with a cracked head and Im contemplating options. I found this bit of info on head interchanges.
"Not directly - the intake ports are too low on the side of the head.
1991-1995 (7120) will work, 1996-1999/2000 (0630) will work. 1999/2000-2007 (0331) will work, but get that from a 2002-up WJ/WK/TJ, since it's the revised casting.
Can I assume from this that anything from 91' on up will work on a 2000? It looks like they went to a new design for the intake/exhaust manifolds in 00' from my manual it looks like they wont bolt up. Also are they any heads that are more desirable than others? Will any mods have to be made to get any of these heads to fit or is it a direct swap?
