It's most likely a bad head gasket (is it running bad?) or a bad gauge.
But it could also be any of these if it is just running hot- clogged vents in the radiator, clogged coolant passages, bad fan or pure antifreeze, improper carb settings, or the radiator not pressurizing,

Could be low on coolant too. But a gauge on a car that old isn't unheard of.
