I would say you have had high rpm valve spring harmonics, where the valve spring and retainer oscillate in a circular motion.
Valve lift alone is not the sole reason that wears valve guides, especially if a roller tipped rocker is used.

Gaz64 here is a video you asked me and a picture of my rocker arms.
Thanks, OliveR
