Valve lifters should be kept in order so they may be reinstalled in their original position. Some engines will have both standard and .010" oversize valve
lifters.
Where O.S. lifters are used, the cylinder case will be marked with a dab of white paint "0.25" (mm) O.S. stamped on the lifter boss.
If the lifters are removed, they must be reinstalled in their original location. If replacement is necessary use lifters with a narrow flat ground along the
lower 3/4 of lifter. These flats provide additional oil to the cam lobe and lifter surfaces.
