I'd pressure test the cooling system and then check to see if you've got any coolant in the oil. It does sound like you've got air getting into the system. This is assuming you've bled it and it's full of coolant. If you crack the drain plug on the oil pan a couple hours after the press test and see water before the oil I'd be looking at the head and cylinder wall of the side that blew the gasket. I'd get the head press tested. A stuck t-stat or no coolant near the t-stat would explain the lack of flow. Or a busted impeller on the water pump. I've never been able to spin a pump by hand and see flow in the radiator.
