I have either blown my head gasket or have cracked my head and was just wondering if the 4.0l heads would work or if anyone had a recomendation on what type of heads to use. who makes the best for the price and all of that good stuff.

 

Assuming you have a 3L, a 4L head isn't interchangeable. I would pull the head to see if its cracked, or you dropped a valve, or the gasket is just bad. When I cracked my heads, I swapped them to a machine shop for a set of rebuilt heads which ran me like, 200 bucks I think...
