(5) Tighten bolts in sequence shown in (Fig. 63),
using the following steps and torque values:
• Step 1: Bolts 1–8 to 48 N·m (35 ft. lbs.)
• Step 2: Bolts 1–8 to 75 N·m (55 ft. lbs.)
• Step 3: Bolts 1–8 to 75 N·m (55 ft. lbs.)
• Step 4: Bolts 1–8 to +90° Turn Do not use a
torque wrench for this step.
• Step 5: Bolts 9–11 to 28 N·m (250 in. lbs.)
(6) Connect catalytic converter to exhaust manifold
with a new V-Band clamp. Tighten V-Band clamp to
10 N·m (100 in. lbs.).
(7) Install camshafts. Refer to procedure in the
section.
(8) Install timing chain and sprockets. Refer to
procedure in this section.
(9) Install water outlet connector (Fig. 61). Refer
to COOLING SYSTEM for procedure.
(10) Install cylinder head covers. Refer to proce-
dure in this section.
(11) Install timing chain cover and crankshaft
damper. Refer to procedures in this section.
(12) Install lower and upper intake manifolds.
Refer to procedures in this section.
(13) Install accessory drive belts. Refer to COOL-
ING SYSTEM for procedure.
(14) Fill cooling system. Refer to COOLING SYS-
TEM for procedure.
(15) Connect negative cable to remote jumper ter-
minal.
VALVE AND VALVE SPRINGS
REMOVAL
(1) With cylinder head removed, compress valve
springs using a Special Tool C-3422-B, Valve Spring
Compressor.
(2) Remove valve retaining locks, valve spring
retainers, valve springs and valve spring seat/stem
seal assembly.
(3) Before removing valves, remove any burrs
from valve stem lock grooves to prevent dam-
age to the valve guides. Identify valves to insure
installation in original location.
INSTALLATION
(1) Coat valve stems with clean engine oil and
insert them in cylinder head.
(2) If valves or seats have been reground, check
valve tip height (A) (Fig. 65). If valve tip height for
intake valve is greater than 47.59 mm (1.8737 in.) or
49.14 mm (1.9347 in.) for exhaust valve, grind valve
tip until within specifications. Make sure measure-
ment is taken from cylinder head surface to the top
of valve stem.
