You get a head ache.
No actually you get this when you get the bill from the mechanic.
The most common signs that your head gasket(s) are gone are that engine oil and antifreeze are mixing. You might find oil in the coolant system or antifreeze in with the oil.
Next most common is that the cooling system gets pressurized as soon as the engine is started and antifreeze gets pushed out into the overflow tank. All this happens before the engine even gets warmed up.
