1. A wood-type golf club head comprising:
- a body having a crown, a sole, and a hollow interior;
a face disposed on the body, the face comprising a perimeter section, a heel vertical section, a toe-vertical section and a central horizontal section connected to each of the heel vertical section and toe vertical section, the face also comprising an upper central region, a lower central region, a heel region and a toe region, wherein the each of the perimeter section, the heel vertical section, the toe-vertical section and the central horizontal section has a first thickness and each of the upper central region, the lower central region, the heel region and the toe region has a second thickness, and the first thickness is greater than the second thickness by at least 0.025 inch, the face composed of a metal material;
wherein the golf club head has a volume ranging from 385 centimeters to 475 centimeters, a mass ranging from 170 grams to 250 grams, a coefficient of restitution ranging from 0.82 to 0.875, a moment of inertial Izz about the Z-axis through the center of gravity of greater than 3000 g-cm2, a moment of inertia Ixx about the X axis through the center of gravity ranges from 1500 g-cm2 to 3800 g-cm2, and a moment of inertia Iyy about the Y-axis through the center of gravity ranges from 2000 g-cm2 to 4000 g-cm2.

Abstract
A face or face insert (40) for a golf club head (20) is disclosed herein. The face (40) has an interior surface (40a) with a first thickness section (200) and a second thickness region (205). The first thickness section (200) preferably has a thickness that is at least 0.025 inch greater than the thickness of the second thickness region (205). In a most preferred embodiment, the first thickness section (205) has a X shape. The face or face insert (40) with variable thickness allows for a face or face insert (40) with less mass in a golf club head (20) that conforms to the United States Golf Association regulations.
