A golf club head for hitting a golf ball farther than existing golf club heads and having a sole, a crown, and a face that includes a lower portion and an upper portion. The sole and crown are cast thinner than most other club heads to promote deformation when striking a golf ball. A parabolic shaped rise in both the crown and sole provide increased lateral strength while aiding in reducing the deformation of the ball at impact. The lower portion of the face has two end portions, and a center portion with the end portions having a first thickness. The center portion and the upper portion of the face have a second thickness that is thicker than the first thickness. In addition, the face includes a channel disposed around its peripheral and having a thickness that is thinner than either the first or second thickness. The overall effect of this invention is to reduce deformation of the golf ball at impact, which reduces the energy lost as heat in the golf ball, resulting in farther drives.
