A face or face insert () for a golf club head () is disclosed herein. The face () has an interior surface () with a first thickness section () and a second thickness region (). The first thickness section () preferably has a thickness that is at least 0.025 inch greater than the thickness of the second thickness region (). In a most preferred embodiment, the first thickness section () has an X shape that is rotated around the Y axis () by at least 10 degrees. In another preferred embodiment, the face has a first thickness section (), a second thickness region (), and a central region () having a third thickness.
