Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
· Tighten the cylinder head bolts.
Tighten
1.Tighten the M11 cylinder head bolts a first pass in sequence to 30 N·m (22 lb ft).
2.Tighten the M11 cylinder head bolts a second pass in sequence to 90 degrees .
3.Tighten the M11 cylinder head bolts (1, 2, 3, 4, 5, 6, 7, 8) to 90 degrees and the M11 cylinder head bolts (9 and 10) to 50 degrees a final pass in sequence Tighten the M8 cylinder head bolts (11, 12, 13, 14, 15) to 30 N·m (22 lb ft). Begin with the center bolt (11) and alternating side-to-side, work outward tightening all of the bolts.

Go to autozone.com and become a member of their web-site. It is FREE. You can then access repair info for your vehicle. There are repair manuals that show pictures and everything. I will look for your torque specs and picture.
  • Clean the cylinder head bolts, apply sealer to the threads, and hand-tighten.
  • Tighten the cylinder head bolts:
    1. M11 cylinder head bolts first pass in sequence to 30 Nm (22 ft. lbs.).
    2. M11 cylinder head bolts second pass in sequence + 90 degrees.
    3. M11 cylinder head bolts (1,2,3,4,5,6,7,8) + 90 degrees
    4. M11 cylinder head bolts (9 and 10) + 50 degrees
    5. M8 cylinder head bolts (11,12,13,14,15) to 30 Nm (22 ft. lbs.). Begin with the center bolt (11) and alternating side-to-side, work outward tightening all of the bolts.
      NOTE The cylinder head gasket displacement can be verified by markings visible on the underside of the right gasket locating tab. Some 4.8/5.3L head gaskets may have 53 stamped onto the locating tab. Some 6.0L head gaskets may have 60 stamped onto the locating tab.
