Dropped valve seats often result from the engine overheating and warping the head Mr Pete. A really good shop will re peen the seats or replace them and then grind them. A dropped seat can destroy the entire engine.
I've read article after article on the support forums and it seems this Ford engine had a propensity of dropping valve seats, and almost always #4. I saw it happen twice.

My engine head and everything else in the current engine is completely rebuilt and further valve droppage is unlikely
I guess I got away from engine work before your engine was in Fords Mr Pete. I have repaired a few Nissans and Mitsubishis with dropped seats and some had several pistons and cylinders destroyed. When the loose seat held the valve down it hit the piston, broke and then moved over into the adjacent cylinder. Count your blessings.

Nothing like the sound of losing a valve...
