1. A golf club head comprising:
- a body having a face wall, a crown wall, a sole wall, a heel wall, a rear wall, and a toe wall, wherein the face wall has an approximately rectangular shape and the face wall has a variable thickness;
wherein the golf club head has a volume ranging from 420 cubic centimeters to 470 cubic centimeters and a mass ranging from 190 grams to 250 grams;
wherein the face wall has an aspect ratio greater than 1.8 for a golf club head;
wherein the golf club head has a moment of inertia about the Izz axis through the center of gravity of the golf club head which is greater than 4000 grams-centimeters squared;
wherein the golf club head has a coefficient of restitution that ranges from 0.81 to 0.94, and the golf club head has a vertical standard deviation of coefficient of restitution of less than 0.0290.

Abstract
A golf club head (42) having a delta of the coefficient of restitution between a geometric face center of the face (72) and a location (806) 0.5 inch sole-ward from the face center that is less than 0.065. The golf club head (42) preferably has a volume ranging from 420 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared.
