Just for testing, remove the thermostat, hook everything back up. With cap off radiator, can you see/feel coolant/coolant passages? With a cross-flow radiator you may be able to drain coolant down enough so you can see the top couple of passages. Start engine, any coolant flow, see/feel? If there is an air-bleed on the cooling system, I couldn't find it? If coolant flow is blocked, try flushing the system.
How do you know it was getting too hot? I don't trust gages on older vehicles.
