probably need a little more info r/e the condition km done compression figures.
my personal take is, and this is very much dependant on what you want to do.
in my case and I'm retired and have no intention to part with my jeep
i have had great results using the later horse shoe inlet manifold and extractors plus 2.5 inch exhaust. next is removing the mechanical fan and going to either two or three electric fans ,removes the horrendous roaring noise plus frees up a small amount of HP, plus the thing just sounds sweeter.
and if you are running larger dia tyres then going to 4.10 gears is a huge improvement.
i generally get 500 km out of a tank of mixed city highway use, stop start makes it really bad really quick.
at 435000 km i have 125 to 135 comp readings, and while it does feel a little tired its only noticeable if i want to be a boy racer ( which I'm not, well ok occasionally hehe)
this is purely my opinion and other may have better advise
