I have a Haynes repair manual. My search here gives me a different set of specs. The manual is way way different. 110 ft lbs? Some here have snapped bolts at 80 ft/lbs. Is this a typo where they mean in/lbs?

Those Haynes manuals can have some questionable stuff in them. You might take a look at the Jeep factory service manual here.

The sticky in the resources section states the following;
I am going to re-torque mine later today. I notices a little oil weeping from between the gasket and the top of the cylinder head.

I've found this site to be pretty helpful for torque specs.

Actually, I'm still a bit confused on the valve cover torque on a '99, 4.0... Is it 85 inch/pounds or 115 inch/pounds? I think I've seen both measurements in multiple places now. Does this spec vary from year-to-year on the TJs? Or, is this the difference between 4 and 6 cylinders? I have plans to change my valve cover gasket soon and am trying to figure this out before I start. Thanks!
Unless your torque wrench cost $400 it doesn't matter. Just get them tight, maybe set it to 100 and be done with it. You are talking about 2.5ft/lbs difference.
