5. After grinding the valve seats or faces, install the valve in cylinder head and check valve installed height by measuring from valve tip to spring
seat. Remove valve from cylinder head and grind valve tip until within specifications. Check valve tip for scoring. The tip chamfer should be
reground (if necessary) to prevent seal damage when the valve is installed.
6. Check the valve spring installed height after refacing the valve and seat. If valves and/or seats are reground, measure the installed height of
springs , make sure measurements are taken from top of spring seat to the bottom surface of spring retainer. If height is greater than
specifications, install a 0.794 mm (0.0312 in.) spacer in head counterbore to bring spring height back within specifications.
