If the valves are being reused, reassemble them into their original locations.
- Coat the valve stems (2) with clean engine oil and install the valves in the cylinder head.
- If the valves or valve seats have been refinished, check the valve tip height (5). If the valve tip height (5) exceeds the specification, grind the valve tip until it is within. Refer to ENGINE SPECIFICATIONS
. Make sure the measurement is taken from the cylinder head surface (7) to the top of the valve stem (2).NOTE:
Make sure that the garter spring is intact around the top of the valve guide seal.
- If removed, install the spring seat and valve guide seal over the valve guide. Refer to SEAL(S), VALVE GUIDE, INSTALLATION .NOTE:

Install a second spring seat (8) in the head counter bore under the original valve spring seat to bring the spring height within specification. Make sure the measurement is taken from the top of spring seat (6) to the bottom surface of spring retainer (1).
