The short story is that corrosion occurs between the rubber head gasket and
the aluminum heads.  Eventually enough corrosion occurs to break the seal
between the gasket and the head and coolant leaks out.  Don't confuse this
coolant gasket with an entirely different seal that is used between the head
and the combustion chamber.
