  1. Clean valves thoroughly. Discard burned, warped and cracked valves.
  2. Remove the carbon and varnish deposits from the inside of the valve guides with a reliable guide cleaner.
  3. Measure the valve stems for wear. If the wear exceeds 0.051 mm (0.002 inch), replace the valve.
  4. Coat the valve stems with clean engine oil and insert them into the cylinder head.
  5. If the valves or seats are ground, check the valve stem height. If the valve stem is too long, replace the cylinder head.
  6. Install new seals on all valve guides. Install the valve springs and valve retainers.
  7. Compress the valve springs with the Valve Spring Compressor (special tool #C-3422-D, Compressor, Valve Spring) and Valve Spring Adapter (special tool #8464, Adapter, Valve Spring). Install the locks and release the tool. If the valves and/or seats are ground, measure the installed height of the springs. Make sure the measurement is taken from the bottom of the spring seat in the cylinder head to the bottom surface of the spring retainer.
  8. Install the cylinder head. Refer to CYLINDER HEAD, INSTALLATION  .
