The limited space and size of shorty headers isn't going to make much of difference from one set to the next. My only advice is to go stainless with whatever you get and make sure to send them off to a third party for a heat barrier coating. They will create better cylinder evacuation so be prepared to run a little lean and remedy this with a higher octane, slower burning fuel.
If you can do without your jeep for the length of time it would take to get the stock manifolds heat barrier coated, I don't think you would be that far behind the nominal gains you will see with headers.
