Ok I think problem is now understood & solved. Fortunately there were no
missing valve keepers once I removed valve cover. My valve head was rebuilt
6 years ago. I suspect that during the valve spring adjustment etc. &
testing this keeper sheared off. The mechanic either couldn't locate it or
since all was OK stopped looking for it-either way-it was in a safe
place-bottom of my sump. The springs etc. are all OK as well. Thanks per
usual from great thoughts, insights, & intrigue. regards, Joe

Sounds like a valve spring stacked solid or the retainer was hitting
the top of the valve guide. Something did not have enough clearance, so the
rocker pushed down on the valve hard enough to shear a keeper.
Check your retainer to guide clearance, and make sure that your
springs have at least 0.010" between each coil at maximum valve lift. It
probably makes sense to inspect all your keepers as well, to make sure none
of the others have been damaged.
