Head gaskets and warped heads are common on the inline 4.0. If you are second guessing the diagnosis there is a tool you can buy that will tell you if exhaust gases are entering your cooling system. Its called a block tester and its fairly easy to use. Instructions do come with the tool. It basically takes a purple color liquid in a chamber you connect it to the radiator with the cap off. Then start the vehicle pull a vacuum with the plunger provided. If the purple liquid turns yellow then you have an internal leak somewhere in the engine.
