1991 Honda Accord Engine head gasket change

I recently had a problem with the car overheating. There was a crack in the radiator- that was changed. A few days later I noticed the car overheat again. There was a hole in the hose behind the engine - the hose was changed. Again a few days later the temperture gauge was going on H. Another hole was found in the heating system hose. That was repaired. After all this it was found that the coolant was leaking into one of the cylinders which was causing the problem. The thermastat was removed and I was told the engine head gasket needs to be changed. Will this really resolve the initial problems? Is it worth putting the additonal work into this car?
