Golf club heads and methods to manufacture golf club heads

Abstract

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head includes a body portion comprising an interior portion, an exterior portion, a toe portion edge, and a back wall portion. The golf club head also includes a face portion, a filler material in the interior portion, a first set of mass portions coupled to the back wall portion, and a second set of mass portions in the interior portion proximate to the toe portion edge. A maximum distance in the interior portion between an inner surface of the face portion and an inner surface of the back wall portion is located between the first set of mass portions and the second set of mass portions. Other examples and embodiments may be described and claimed.
