- Left rear head bolt must be installed in cylinder head before installation. Install cylinder head. Ensure that head is seated on dowel pins. Install head bolts.
- Tighten head bolts in proper sequence. See Figure. Tighten head bolts in 3 steps to specification. See TORQUE SPECIFICATIONS table. Install push rods in original location with hardened end upward. Hardened end should be indicated by paint mark.
- Install rocker arm shafts. Special procedure must be used to prevent damage to pistons and valves. See ROCKER ARM.
