No, sir, that is not correct. With the spring in its loaded condition (shaft rotated clockwise as viewed from the front) the flap should be "standing up". When you rotate the shaft counterclockwise (viewed from the front) the top of the flap should move to the left until it deflects all the exhaust down and away from the intake.
It is very much worth your while to get the
good gaskets for the manifolds-to-head and intake-to-exhaust junctions.
