Valve and Spring Installed Height
VALVE AND SPRING INSTALLED HEIGHT1. 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 is greater than 43.65 mm (1.7185 inch) intake or 45.98 mm (1.8102 inch) exhaust, 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. 31). Ensure that the garter spring is intact around the top of the rubber seal.
4. Place valve spring (color-coded end facing up (Fig. 30)) and valve retainer into position on spring seat (Fig. 31).
5. Compress valve springs with valve spring compressor C-3422-D and adapter 6526, install locks and release tool.
6. If valves and/or seats are refaced, measure the installed height of springs (B) (Fig. 29). Measurements are 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.
