Valves kinda 'continually' grind themselves in... you would end up with =
an ill seated valve, that could wobble slightly in its hole, and =
eventually break its stem....=20

You could spline a single shaft to keep it from spinning also. But, =

rotate now by design, right? Why, and what would happen to an oddly =

valve that couldn't rotate?
