VALVES, VALVE SPRINGS AND VALVE SEALS
Installation
1. Coat the valve stems with engine oil. Install the valves in the valve guides.

NOTE: Make sure the valves move up and down smoothly.

2. Install the spring seats on the cylinder head.





3. Install the valve seals using the valve guide seal installer.

NOTE: Exhaust and intake valve seals are not interchangeable.





4. Install the valve spring and valve retainer, then install the valve spring compressor. Compress the spring and install the valve keepers.

NOTE: Place the end of the valve spring with closely wound coils toward the cylinder head.





5. Lightly tap the end of each valve stem two or three times with a plastic mallet to ensure proper seating of the valve and valve keepers.

NOTE: Tap the valve stem only along its axis so you do not bend the stem.
