4.2 or 4.0?

I know I'm new here, but I'm looking for advice. My I4 in my 95 YJ is getting pretty high on mileage and already has one warped cylinder head (not my doing). I'm looking at swapping in either the 4.0 or the 4.2, but can't decide which. Any suggestions?

Here are a couple threads dealing with that question:

4.0 vs. 4.2 - JeepForum.com


These threads cover the basic pros/cons of the two engines. Go through these two threads and if you have more questions ask away
