  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). See Fig 1. If valve tip height is greater than 43.65 mm (1.7185 in.) intake or 46.48 mm (1.8299 in.) 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 stem. See Fig 3. Ensure that the garter spring is intact around the top of the rubber seal.

If height is greater than 38.75 mm (1.5256 in.), install a 0.762 mm (0.030 in.) spacer in head counterbore under the valve spring seat to bring spring height back within specification.
