Reassemble Cylinder Head Components
(See Figure 11-29 thru 11-31)
1. Rocker Bridge Heads Only - Install the rocker
bridge to the cylinder head. Make sure the small
(counterbored) hole is toward the exhaust port
side of the cylinder head. Secure the rocker
bridge with two M6 hex cap screws. Torque the
screws to 9.9 N·m (88 in. lb.).
2. Install the intake valve stem seal, intake valve,
spring seat, intake valve spring, and valve spring
cap. Compress the valve spring using a valve
spring compressor and install the keepers.
3. Install the exhaust valve, valve spring, and valve
spring cap. Compress the valve spring using a
valve spring compressor and install the keepers.
NOTE: Exhaust valve rotators are no longer
used. Do not attempt to install rotators if
a new head is being installed, or if head
did not use one originally.
