Several folks make cams that don't require higher lift... but, given that you describe the engine as "tired", you can bet that the valve springs in there are as well. Considering what you are going to spend on a cam, another 100 bucks or so for new springs would be a wise investment.
Look for cams that are 'computer friendly' and do NOT require reprogramming. (they are out there.
) As you have a 95, you options in that realm are extremely limited. Might also want to look for a mopar performance PCM. That will widen your cam choice somewhat, and will give a nice kick in and of itself.
If you are going to tear the engine down, be warned in advance that it is highly likely that your heads are cracked between the valve seats. (lousy castings from the factory.) Spending money on the stockers is a waste. There are better made castings available out there. (clearwater, and odessa.) You can probably figure around 600 for some stock replacements.
How many miles on your current motor? Fixed the plenum yet?
