1 Regardless of whether or not a head was sent t o an automotive
repair shop for valve servicing, make sure it's clean before beginning
reassembly.
2 If a head was sent out for valve servicing, the valves and related
components will already be in place. Begin the reassembly procedure
with Step 8.
3 Install new seals on each of the intake valve guides. Using a ham-
mer and a deep socket or seal installation tool, gently tap each seal
into place until it's completely seated on the guide (see illustration).
Don't twist or cock the seals during installation or they won't seal prop-
erly on the valve stems. The umbrella-type seals (if used) are installed
over the valves after the valves are in place.
4 Beginning at one end of the head, lubricate and install the first
valve. Apply moly-base grease or clean engine oil t o the valve stem.
5 Drop the spring seat or shim(s) over the valve guide and set the
valve springs, shield and retainer (or rotator) in place (see illustrations).
6 Compress the springs with a valve spring compressor and carefully
( V 6 only) in the lower groove of the valve
install the O-ring oil seal
stem. Make sure the seal isn't twisted
the groove (see illustration). Position the keepers in the upper groove,
