Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:
Long bolts:
Short Bolts:
Here is a pic of the sequence

SOURCE: head bolt torque spec
Always use new head bolts.
1)tighten to 40ft/lbs
2)back off 1/2 turn
3)tighten back to 40ft/lbs
4)tighten an additional 90 degrees
5)tighten an additional 90 degrees.

STARTING OUT YOU HAVE TO REPLACE THE OLD BOLTS DUE TO STRETCHING.BESURE TO USE NEW BOLTS LUBRICATE NEW BOLTS IN OIL.BESURE TO USE TORQUE SEQUENCE GUIDE OR PHOTO.YOU GOING TO MAKE THREE PASSES * FIRST* PASS YOU TORQUE ALL HEAD BOLTS TO 12 TO 18 FT LBS * SECOND *PASS YOU TORQUE ALL BOLTS TO 26 TO 33 FT LBS.*THIRD PASS YOU TORQUE IT TO 44 FT LBS.THATS THE FINAL TORQUE.
Cylinder head bolt torque sequence-2.0L and 2.3L engines
Apply engine oil to the bolt threads and tighten the cylinder head bolts, in sequence, using the following 6 Steps:
Fig. Cylinder head bolt torque sequence-3.8L engine
Fig. Tighten the cylinder head bolts using the following sequence-31L and 3.4L engines
for the head
Step 1: Bolts 1 - 8 to 61 N·m (45 ft. lbs.)
† Step 2: Bolts 1 - 8 to 88 N·m (65 ft. lbs.)
† Step 3: Bolts 1 - 8 (again) to 88 N·m (65 ft. lbs.)
† Step 4: Bolts 1 - 8 turn an additional 1/4 Turn.
(Do not use a torque wrench for this step.)
NOTE: Bolt torque after 1/4 turn should be over 122
N·m (90 ft. lbs.). If not, replace the bolt.
