00 Cherokee Cylinder head torque specs

I am putting in a new head. I have the FSM for a 99 and am wondering if the torque specs are the same.

For the 99 4.0 it states - after the initial torque sequence.

Bolts 1 through 10 to 149 Nm (110 ft. lbs.)
torque.
Bolt 11 to 13 Nm (100 ft. lbs.) torque.
Bolts 12 through 14 to 149 Nm (110 ft. lbs.)
torque.

Can anyone with a 2000 XJ FSM tell me if it is the same spec?

Here is it from the the 00 manual. (for w/e reason my 01 has the 00 in it, I guess they must be the same)

Quote:
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.

From the 2000 FSM

.
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 correct
torque.
(f) If not already done, clean and mark each bolt
with a dab of paint after tightening. Should you
encounter bolts which were painted in an earlier
service operation, replace them.

<-- Front of engine, bolt numbers torque sequence.
