After several adjustments with the air dams I placed a small scoop on the upper intake of cylinders 2,4,6 which evened everything out, but would still get too high in high power climb. I then extended the flange lip on the bottom of the cowl about an inch and 1/2 by riveting a piece of aluminum .o25. Never have any problems now. Attached is picture.
