after starting up the car and letting it run the coolant level in the radiator never went down after initial filling it looks like nothing is circulating in the radiator what could be the problem

are you certian the thermostat should have been open?

you need to do a pressure check on it probably got a air bubble somewhere or the thermostat is in upside down

You didn't happen to buy a reverse rotation pump did you?

5 bux says the thermostat is in backwards.

I tried running the car with no thermostat and still had no circulation in the radiator and i was having the same problem with the old water pump

flush and clean.

You say you just did the heads....pull them and make sure you didn't install your head gaskets backwards which would block the water ports

While the intake is off make sure your flow isn't blocked by rtv and/or other crap that builds up in 40 yr old blocks.

all gaskets were replaced correctly . All this was done as the car overheated and the gaskets were suspect
