Glad you stopped driving it before it snapped the belt, even if the outcome looks bad. Could be much worse.
Didn't have the choice on the 100hp engine, as it was totally knackered before I got my hands on it.
However, in this case I would probably lean towards replacing the head with a good second hand one, providing the car is generally in good condition. (I would also replace the engine mount as its been stressed in unintended directions)
It's a fairly simple job (apart from the cam belt, which people seem to regularly invent new ways to screw up). Least amount of dismantling to fix the problem.
I would consider a complete engine swap if it needed a clutch, or it had any other problems which could be fixed at the same time.
