Valve Inspection
1. Remove all carbon from valves with a soft wire wheel
or brush.
2. Check valve face for runout, pitting, and burnt spots.
To check for bent valve stems, mount valve in a drill
or use “V” blocks and a dial indicator.
3. Check end of valve stem for flaring, pitting, wear or
damage (A).
4. Inspect split keeper groove for wear or flaring of the
keeper seat area (B). NOTE: The valves can be re-
faced or end ground, if necessary. They must be
replaced if extensively worn, burnt, bent, or
damaged.
5. Measure diameter of valve stem with a micrometer in
three places, then rotate 90 degrees and measure
again (six measurements total). Compare to
specifications.

Intake: 0.2356" + 0.00039"
(5.985 + 0.01 mm)
