1993 Cherokee Sport 4X4 4.0 Stock

With nearly 250k mi on this engine without any major work done to it, I figured it was time to do a valve job. Found a broken head stud and discovered one of my engine mounts to be shot. Need to know what other things I should be looking for and changing out while I have access. What type of activities can give me the most "bang for the buck".

Thanks.

 

With that many miles on it, I would change the cam and lifters, and a new timing chain set would be a good thing to throw in also.
