Just because coolant wasn't getting into the cylinders doesn't mean the gasket wasn't leaking. What does the oil look like?
I would clean and check the deck surface for cracks and straightness, it should be fine if the engine hasn't been severely abused or overheated.
Next run a thread chasing tap through all the head bolt holes checking for obvious signs of a problem. If it's all good go back with a new head gasket, coat all the head bolts with pipe thread sealer then torque to proper spec.
