The lifter is the most precisely machined part in the engine. The plunger OD is matched to the lifter body ID; the close tolerances are required to give the correct amount of bleed down. For that reason, there is a chance you might need to go through more than one lifter to find a good match to the old plunger OD. The MAIN thing is that the plunger not be too tight. Slightly loose will still perform OK, although there's a chance there could be some slight tapping at idle. But if the lifter and cam cannot for whatever reason be replaced as a set, this is STILL preferable to putting a new lifter on a used cam. | The lifter is the most precisely machined part in the engine.
