If I were you, replace the chain and all the components. With the mileage, it is time.
I would also do both heads, not 1. Have them checked for cracks and get the valves cleaned up. Replace the stem seals and have the cams checked for excessive wear.
No short cuts in engine work. It is long and labor intensive and any short cut will result in doing the job over again.
Tkae your time and do it right. If it overheated and blew the gasket, I would look hard at the thermostat, replace the water pump while you are there and have the radiator flow tested.
