Valve & 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. If valve tip height for intake valve is greater than 47.59 (1.8737") or 49.14 (1.9347") for exhaust valve, grind valve tip until within specifications. Make sure measurement is taken from cylinder head surface to the top of valve stem. See Figure.
  3. Install valve seal/spring seat assembly over valve guides on all valve stems. Ensure that the garter spring is intact around the top of the rubber seal.

  5. Compress valve spring with a valve spring compressor.

  7. If valves and/or seats are refaced, measure the installed height of springs (B). 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"), install a 0.762 mm (0.030") spacer in head counterbore under the valve spring seat to bring spring height back within specification. See Figure.
