BTDT. Not a good thing. Generally means that the guide is too tight a fit
on the valve stem. When you run the engine harder and hotter the problem
gets worse. Since the guide is restrained by the heavy head casting, when
it gets hot it expands inwards constricting on the valve stem. When all is
new, one tight guide usually means the others are very near to hand. When
I had this problem I had the ehgine fairly hard for 1000 miles in one week,
but it would never loosen up, had to pull the head again to resize the
valve guides.
