Chilton'* 28200 gives 89 in-lb twice in sequence for the '95 lower, and 89 in-lb for the upper in sequence. For 96-99, it lists 11 ft-lb for the lower in sequence, and 89 in-lb for the upper in sequence. Threadlocker is recommended for the LIM bolts. I use threadlocker on the LIM and the UIM bolts.
BTW, take something sharp and strong like an awl, or a heavy needle, and poke the outside top of the UIM. Then try the same thing on the EGR bore, especially near the bottom, and see if it is as hard as the outside. Sometimes a coating of carbon hides rotten plastic.
