Once upon a time, at Danny Otey's shop, we had an early on the lift 
trying to diagnose an intermittent annoying clicking that came and 
went.   We were gonna look close, expecting to maybe find a bad lifter.

While the engine was running on the lift, rocker cover off, we waited 
a bit and the clicking started... one valve retainer was changing its 
height, sometimes returning to the same level as the rest, sometimes 
not.   That head came off the engine, swapped it out with another good head.

I removed the retainer, spring, and valve, and noted that the "seat 
wasn't seated", popped it out of the head with a screwdriver.   It 
looked perfect, not a nick, but likely wouldn't have if it had come 
completely loose with the engine running.

It's still on the carnage shelf in my basement.
