Oversized guide sizing are for the OD, not the ID for the valve stem. These are required if your guides have been removed numerous times and the head has lost enough material where the holes have gotten large.

Supertech Valve Guides are precision-machined from high quality Manganese Bronze material. Designed to be used in combination with Supertech's low friction black nitrided valves to provide the best solution for both performance and durability.
