Utilizing oil restrictors can reduce important oil flow to the tappets and will cause needle bearing failure, axle failure, and severe tappet body damage. Be sure that your oiling system provides adequate oiling to cool and lubricate your roller tappets and the balance of your valve train components.

Since the valve train in a typical overhead valve engine contains numerous components which may or may not be matched, care must be taken to avoid potential issues which may affect the overall performance of the lifters and the engine. These considerations can be best described in two categories: Mechanical Interference and Valve Train Geometry.
