JF -
The setup I am using, I believe was originally developed by Carroll Smith while working the GT-40 program with another famous Carroll.

Anyway - the large (Overflow) tank is actually under suction from the water pump. The two inflows at the top are designed to remove air from the radiator and the top of the swirl tank.
Other than that (the Overflow tank plumbing) - it is similar to your drawing.
*** Update: Here is a nice diagram of my setup, taken from one of George's detailed threads. Scroll down to the cooling system part.
