Re: 4.0L head swap donor question
The '97 head would be a great choice if you were going to go FI, but if you want to keep your carb, go with a '91 - '95 head. The old manifolds won't bolt up to a '96 or newer head - they changed the bolt pattern on the side of it, so make sure you get both matching manifolds. I found this out when I put a '98 head on my '80. I ended up going FI, which wasn't all that hard, (although at the time it seemed overwhelming, but looking back was a cake walk) and I really love it. I retro fitted a '94 HESCO FI kit on mine, which made the instalation of the FI simpler for me, but the newer FI can be done as well.
