Just a thought. Had a friend with a 65 Comet that developed a major leak while he was driving it. It was blowing very hot radiator fluid on him and he wrecked the car. Now, this was a later pressurized system, but something to keep in mind. A major heat core leak while driving is not a good thing, so might want to be sure the core is in good shape. Any repair should be of good quality. Lability might be a shops concern for a repair of this type inside the car.
