manifold heat control valve

Mine is also not working right, and no one (the Dodge dealer, Napa auto parts, etc.) can seem to locate a rebuild kit, and all the slant sixes are gone from the pick your parts around me. I have a 67 with the square weight (as opposed to the later years ound weight). If I am standing at the bumper in front of the car and looking toward the windshield and at the engine, it will be in what position if i turn it clockwise? so the top of the square moves toward the driver side? I know it only turns about 1/4th of a circle, but I want to make sure that in my situation in southern california, it is not sending hot exhaust to the intake.
Thanks!
