5. Check the valve spring installed height after refacing the valve and seat (Fig. 29).
VALVE AND SPRING INSTALLED HEIGHT
1. Coat valve stems with clean engine oil and insert them in cylinder head.
2. If valves or seats have been refaced, check valve tip height (A) (Fig. 29). If valve tip height for intake valve is greater than 47.59 (1.8737 inch) or
49.14 (1.9347 inch) for exhaust valve, grind valve tip until within specifications. Make sure measurement is taken from cylinder head surface to
the top of valve stem.
3. Install valve seal/spring seat assembly over valve guides on all valve stems (Fig. 30). Ensure that the garter spring is intact around the top of the
rubber seal.
4. Position valve springs and retainer on spring seat (Fig. 30).
5. Compress valve spring with a valve spring compressor.
6. Install retainer locks and release tool.
7. If valves and/or seats are refaced, measure the installed height of springs (B) (Fig. 29). Measurement is taken from top of spring seat to the bottom
surface of spring retainer. If height is greater than 38.75 mm (1.5256 inch), install a 0.762 mm (0.030 inch) spacer in head counterbore under the
valve spring seat to bring spring height back within specification.
