You'll hear a loose valve clicking, but one that gets too tight will eventually not be able to cool itself (not enough solid contact with the head material each cycle) and you'll burn it. Then you are looking at a head rebuild at minimum, or maybe the whole engine depending on how the destruction dominoes fall.
It's a gamble to let them go that long. I wouldn't, but it's your call.
