thanks guys! now i know i can be safe while looking around. ( i will stay 1995 or newer) now if i can ask another questions, which years does everyone prefer?
I don't know if the wranglers used the 0331 heads nor do I know if you want to buy that new of a vehicle, but the 99' 00' 4.0s with the 0331 casting head had problems with cracking. You can identify the head by looking inbetween the #3  cylinders on the driver's side of the engine right beside the valve cover.
