- Tighten all bolts in sequence (1 through 14) to 30 Nm (22 ft. lbs.) torque.
- Tighten all bolts in sequence (1 through 14) to 61 Nm (45 ft. lbs.) torque.
- Check all bolts to verify they are set to 61 Nm (45 ft. lbs.) torque.
- Tighten bolts in sequence:
- Bolts l 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.).

CYLINDER HEAD SURFACE VARIATION

Maximum Allowable Surface Variation .008"

Use a straightedge and feeler gauge to check the flatness of the engine cylinder head and block mating surfaces.

CYLINDER HEAD BOLT RE-USABILITY

The Cylinder head bolts should be examined BEFORE reuse. If the threads are necked down, the bolts should be replaced. Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale the bolt should be replaced.
