Measure valve stem-to-guide clearance as follows:
Install valve into cylinder head so it is 15 mm (0.590 inch.) off the valve seat. A small piece of hose may be used to hold valve in place.
Attach dial indicator Tool C-3339 to cylinder head and set it at right angle of valve stem being measured. See Fig 1.
Move valve to and from the indicator.
Note dial indicator reading and compare to engine specifications. See SPECIFICATIONS .

NOTE: Replace cylinder head if stem-to-guide clearance exceeds specifications, or if guide is loose in cylinder head.
