- Position maximum lift point of camshaft lobe opposite valve lifter. See Fig 1
. Using flat knife type gauge, measure clearance between camshaft lobe and valve lifter. See VALVE CLEARANCE SPECIFICATIONS

.NOTE: Apply motor oil to camshaft and lifters before adjusting valves.
- Measure adjusting shim with micrometer and compare with desired clearance. Install replacement shim(s) as necessary to obtain correct valve clearance.
- After all necessary adjustments are made, rotate engine several times and recheck valve clearances. Readjust valve clearances if necessary. Replace rocker cover gasket (if necessary) and reinstall rocker cover.
