valve ajustment measurements on 1998 Pontiac Trans Sport

What are the valve ajustment measurements ? so that my home machanic can ajust them .I drove the car on low oil, now it knocks.

This vehicle doesn't have adjustable valves, and if the engine is knocking after driving with low oil, then you likely have a more serious problem with the engine.
