valves are supposed to rotate as they work. some engines even have rocker offsets to make the valve rotate as it is actuated. you cant stop it anyway, unless you had a square valve.

@JasonMann8 normal speed with a strobe light cycling just slightly less or more than the rpm of the engine. eg: 8000 rpm engine with a 7999 or 8001 flash per minute strobe. Very cool effect

The down fall to a pushrod engine the springs have to be strong to shove the rocker arm up and push rod and the lifter then the springs are so stiff the valve has to be heavy and beats the crap out of the seats. Go dohc

When we studied AutoMech in the 1960s, we were taught that the valves were EXPECTED to rotate during their operation, and their followers were designed to create this desired feature. Rotating prevented hotspots or build-up of foreign objects on the valve seats. I still don't see rotation as a 'bad' thing. The valve stem wobble, however, is not something I would want, since it would cause the valve to leak around the seat.
Thnx for posting this very interesting vid.
