and do a search on 4.0 head conversion, heck, do one here, do one on pirate, do one on JU, and do one on google, should have more info than you could possibly want.

and yes the head will swap, the 4.0 intake/exhaust manifolds will not work unless you swap the head. it is not a straight bolt on a bit of work has to be done, but it is possible, it is a good swap, and you can get injection to boot (if you go that way [img]images/graemlins/grin.gif[/img])

Re: 4.2l ?

I'll chime in on the profile thing. If you don't know what we're talking about go back and read the first post (sticky note) on the main page. Filling out your profile helps people to give better advice.
As far as the 4.0L head and intake, go to Jaffer's page Jaffer, he has an extremely good write up on his conversion. Also if you do a search you can find tons of information on the subject.
Welcome to that BBS and feel free to ask questions and give answers.
