had 11 cracks on my head, mostly all on the valve seats... ran it like that for about 150 miles before i took off the head to get it fixed.(this was when i just bought the car).. the more i would run it , the more bubbles i would get into the radiator...meaning pressurization in the coolant which isn't good. but i wouldn't think the seats would literally fall out... but cracks need to get fixed. b/c your car will run like doo doo.

The stock heads don't use replaceable seats so no chance of dropping one. They are just surface hardened in the seat area.
