from the cylinder head. This will ensure that the
valves are properly placed during engine
reassembly.
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 (A) for flaring, pitting, wear
or damage. Inspect split keeper groove (B) for wear
or flaring of the keeper seat area.
NOTE: The valves can be re-faced or end
ground, if necessary. They must be replaced if
extensively worn, burnt, bent, or damaged.
4. Measure diameter of valve stem with a micrometer in
three places, then rotate 90 degrees and measure
again (six measurements total). Compare to
specifications.
