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

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

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
