You don't want ANY restriction in your lower radiator hose. It's best to use the pipe arrangement with a smooth, full-diameter bend and to use pipe the same OD as the OD of the radiator and water pump connections. Using the pipe and short lengths of straight radiator hose eliminates any need of an internal spring, and it assures full, unrestricted coolant flow. Stainless, mandrel-bent pipe would be ideal. Or brass. The original pipes were mild steel. The bend, or curve, is a little more than 90 degrees.
