2. Starting at one end of the head, lubricate and install the first valve. Apply moly grease or clean motor oil to the valve stem.
3. Install the spring seat or adjusting washer over the valve guides then replace the spring screen and retainer (see illustration).
4. Compress the springs with the tools. Place the holders in the grooves, then slowly loosen the tool and make sure the holders are seated correctly. If necessary, secure the holders in place with a small amount of grease.
5. Perform the same procedure with the remaining valves. Do not mix up the parts from different valves - install them only with each other.
6. Check the installed valve spring height with a 1/32" graduated ruler or a dial gauge. Measure from the top end (seat) of the spring or adjusting washer to the bottom retainer (see illustration). If the height is greater than specification, shims can be placed under the spring to adjust it.
Caution: Do not, under any circumstances, place shims under a sagging spring that is less than the specified height.
7. Apply "moly" grease to the outside surfaces of the valve levers and pivot pins, then install the pins and levers into the cylinder head. Screw in the bolts 3-4 turns (if installing a V-shaped six-cylinder engine head, the bolts should be tightened in accordance with the recommendations given in the specification).
