Paul said: Jeff! I'd have to say that came from pre-ignition, not from operating in the normal, Lycoming-recommended range, unless it was from an engine operated above their limits. 
 
I am quite sure the piston damage was a result of detonation, severe and prolonged detonation.  If it was pre-ignition, it would have a hole through the center of the piston.
