CAUTION:

The magnetic timing wheels (1) must not come in contact with magnets (pickup tools, trays, etc.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.

    CAUTION:

    The cylinder head bolts are tightened using a torque plus angle procedure. The bolts must be examined BEFORE reuse. If the threads are necked down the bolts must be replaced.

    NOTE:

    Typical cylinder head bolt shown in illustration.

  4. Check cylinder head bolts for necking by holding a scale or straight edge against the threads. If all the threads do not contact the scale (2) the bolt must be replaced.

    NOTE:

    Right head gasket shown in illustration, left head gasket similar.

    CAUTION:

    When cleaning cylinder head and cylinder block surfaces, DO NOT use a metal scraper because the surfaces could be cut or ground. Use ONLY a wooden or plastic scraper.

  5. Clean and prepare the gasket sealing surfaces of the cylinder head and block. Refer to ENGINE GASKET SURFACE PREPARATION  .
    CAUTION:

    Non-compressible debris such as oil, coolant or RTV sealants that are not removed from bolt holes can cause the aluminum casting to crack when tightening the bolts.

  6. Clean out the cylinder head bolt holes in the engine block.
    WARNING:

    The multi-layered steel head gaskets have very sharp edges that could cause personal injury if not handled carefully.

    CAUTION:

    The installation of the cylinder head gaskets are not interchangeable between the left and right cylinder heads. They are clearly marked (3) with "R" for right and "L" for left. They must be applied on a dry surface, without the use of any adhesives.

  7. Position the new cylinder head gasket (1) onto the locating dowels (2).

  8. Position the cylinder head onto the cylinder block. Make sure the cylinder head seats fully over the locating dowels.
    NOTE:

    Do not apply any additional oil to the bolt threads.

  9. Install the eight cylinder head bolts finger tight.
  10. Tighten the cylinder head bolts in the sequence shown in illustration, following this 9 step torque plus angle method. The torque sequence must be used for each step. Tighten according to the following torque values:
    • Step 1: All to 30 N.m (22 ft. lbs.)
    • Step 2: All to 45 N.m (33 ft. lbs.)
    • Step 3: Re-tighten all to 45 N.m (33 ft. lbs.)
    • Step 4: All + 125° Turn (optional angle if 125° rotation cannot be accomplished in one motion; tighten all by turning 35° followed by tightening all by turning 90°) Do not use a torque wrench for this step. 
    • Step 5: Loosen all fasteners in reverse of sequence shown in illustration
    • Step 6: All to 30 N.m (22 ft. lbs.)
    • Step 7: All to 45 N.m (33 ft. lbs.)
    • Step 8: Re-tighten all to 45 N.m (33 ft. lbs.)
    • Step 9: All + 130° Turn (optional angle if 130° rotation cannot be accomplished in one motion; tighten all by turning 40° followed by tightening all by turning 90°) Do not use a torque wrench for this step. 
    NOTE:

    For engine builds using a new block follow steps  1- 9. For engine re-builds (reuse block) follow step  6- 9.

    CAUTION:

    Do not rotate the camshafts more than a few degrees independently of the crankshaft. Valve to piston contact could occur resulting in possible valve damage. If the camshafts need to be rotated more than a few degrees, first move the pistons away from the cylinder heads by rotating the crankshaft counterclockwise to a position 30° before-top-dead-center. Once the camshafts are returned to their top-dead-center position, rotate the crankshaft clockwise to return the crankshaft to top-dead-center.

    NOTE:

    If the hydraulic lifters are being reused, reassemble them into their original locations.

  11. If removed, install the hydraulic lifters. Refer to LIFTER(S), HYDRAULIC, INSTALLATION .
    NOTE:

    If the rocker arms are being reused, reassemble them into their original locations.

  12. Install the rocker arms and camshafts. Refer to CAMSHAFT, ENGINE, INSTALLATION .
  13. Rotate the camshafts clockwise to TDC by positioning the alignment holes (1) vertically.

  18. Press the left intake cam phaser onto the intake camshaft, install and hand tighten the oil control valve.
    CAUTION:

    Always reinstall timing chains so that they maintain the same direction of rotation. Inverting a previously run chain on a previously run sprocket will result in excessive wear to both the chain and sprocket.

  19. Drape the left side cam chain over the left intake cam phaser and onto the idler sprocket (1) so that the arrow (3) is aligned with the plated link (2) on the cam chain.

Press the exhaust cam phaser onto the exhaust cam, install and hand tighten the oil control valve (2).
    NOTE:

    Minor rotation of a camshaft (a few degrees) may be required to install the camshaft phaser or phaser lock.
