It's 85 INCH-pounds. Unless you have a in-lb torque wrench, the next best thing is "wrist tight" with a quarter inch drive socket and ratchet. They don't have to be killer tight, just enough to compress the gasket a little. Recheck them in a day or so in case the gasket takes a set.
Tightening sequence is not important, but if you are worried, start in the middle and work out to the two ends.
I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.
