A good friend sent these links to these videos showing the valve springs while they are being run at different RPM's. While you are watching the videos notice how they are spinning and bouncing and then look really close at the valve stem and see that the valve is also spinning. You will have to download them and then view them on your computer. They are large files but well worth the watch. Just another example of things that make you go "Hmmmm"
