  1. Position the new cylinder head gaskets onto the cylinder block.
  2. Position the cylinder heads onto head gaskets and cylinder block.
  3. Starting at top center, tighten all cylinder head bolts, in sequence, to 68 N.m (50 ft. lbs.) torque (Fig 1 ). Repeat procedure, tighten all cylinder head bolts to 143 N.m (105 ft. lbs.) torque. Repeat procedure to confirm that all bolts are at 143 N.m (105 ft. lbs.) torque.
    CAUTION: When tightening the rocker arm bolts, be sure the piston in that cylinder is NOT at TDC. Contact between the valves and piston could occur.
  4. Install push rods and rocker arm assemblies in their original positions. Tighten the bolts to 28 N.m (21 ft. lbs.) torque.
  5. Install the intake manifold (Refer to ENGINE/MANIFOLDS/INTAKE MANIFOLD-INSTALLATION  ) and throttle body assembly.
  6. Install exhaust manifolds (Refer to ENGINE/MANIFOLDS/EXHAUST MANIFOLD-INSTALLATION  ).
  7. Adjust spark plugs to specifications. Install the plugs and tighten to 41 N.m (30 ft. lbs.) torque.
  8. Install coil wires.
  9. Connect coolant temperature sending unit wire.
  10. Connect the fuel injector harness.
  11. Connect the vacuum supply hoses to the intake manifold.
  12. Connect the heater hoses and bypass hose.
  13. Install distributor cap and wires.
  14. Connect the accelerator linkage and, if so equipped, the speed control and transmission kick-down cables.
  15. Install the fuel supply line.
  16. Install the generator and accessory drive belt (Refer to DRIVE BELTS ). Tighten generator mounting bolt to 41 N.m (30 ft. lbs.) torque.
  17. Install the intake manifold-to-generator bracket support rod. Tighten the bolts.
  18. Install cylinder head covers. (Refer to ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S)-INSTALLATION  ).
  19. Install closed crankcase ventilation system.
  20. Connect the evaporation control system.
  21. Install the resonator assembly, air in-let hose and air cleaner.
  22. Install the heat shields. Tighten the bolts to 41 N.m (30 ft. lbs.) torque.
  23. Fill cooling system (Refer to STANDARD PROCEDURE--REFILLING COOLING SYSTEM ).
  24. Connect the battery negative cable.
