I could be wrong but from what I know it looks like the valves in these pictures are installed wrong. Normally, with these screw in valves, the threaded end screws into the intake or carb base with the threads at the vacuum source and the hose running to the valley pan, valve cover, or area where the older road draft tube went. Try reversing the valve and see what that does.
