The cam on a small block is designed to rotate in the same direction as the crank. With a chain it does naturally. When you use a gear drive the cam would rotate in the opposite direction, as in the picture, without the counter gears. i'm assuming the the cam in the pic is ground to rotate opposing the crank.
