should valves rotate ?

The difference may lurk in the valve stem or guide.

I have gotten this from a couple other guys I respect , so I will definitely pay some attention to the keeper too.
I am curious if I have a bad spring and that led to floating the one valve too.
If I am lucky , I will be able to fix it without pulling the head.
But if not , I guess that is the price of having fun.
I really appreciate the help a lot Guys.
