Torque Specs on Head Bolts

I am in the middle of putting my Jeep back together and cannot find my Haynes manual after recently moving. Anyone have the torque specs for the head bolts on a 96 4.0?

Per the FSM, torque all head bolts in sequence in a spiral pattern to 22 ft-lbs, then 45 ft-lbs. The final torque value is to 110 ft-lbs on all head bolts except the driver's side front, which is torqued to 100 ft-lbs with Loctite 592 (PTFE) on the threads. All other head bolts are installed with dry threads.

From the FSM:

(4) Coat the threads of stud bolt No.11 with Loc-
tite 592 sealant, or equivalent.
(5) Tighten the engine cylinder head bolts in
sequence according to the following procedure (Fig.
56).
CAUTION: During the final tightening sequence,
bolt No.11 will be tightened to a lower torque than
the rest of the bolts. DO NOT overtighten bolt
No.11.
(a) Tighten all bolts in sequence (1 through 14)
to 30 Nm (22 ft. lbs.) torque.
(b) Tighten all bolts in sequence (1 through 14)
to 61 Nm (45 ft. lbs.) torque.
(c) Check all bolts to verify they are set to 61
Nm (45 ft. lbs.) torque.
(d) Tighten bolts in sequence:
• Bolts 1 through 10 to 149 Nm (110 ft. lbs.)
torque.
• Bolt 11 to 135 Nm (100 ft. lbs.) torque.
• Bolts 12 through 14 to 149 Nm (110 ft. lbs.)
torque.
(e) Check all bolts in sequence to verify the cor-
rect torque.

It's all good, Jeff. I just went with the condensed version.

Thanks guys, she's back together! I don't know how the back right bolt is going to be because I had to use a swivel... but there's only one way to find out. Thanks again.
