Water pump gasket leak.
1964 421 water pump to timing cover gasket leak. The water pump is fairly new (from Ames) and I don't see anything wrong with it or timing cover. I have replaced the gasket that came with it twice with new gaskets for seepage.. It seeps coolant out around the gasket. The first 2 gaskets were coated with Permatex High Tack spray. The last with Permatex Forma Gasket #2. It can leak at any point around the pump. To stop the leaking I've added a "stop leak" to the coolant. It seems to have worked at least for now. Is it possible the gaskets are just too old and aren't sealing. They can't be producing many of the gaskets now.
