I just replaced the head gaskets, but the motor overheats. I have checked the thermostat and the water pump.

The head could be cracked-check the oil if its milky

I had the heads sent to a machine shop. They were milled down and had new valve seals installed. They were also checked (magnafluxed)for cracks. Any other ideas.
