Golf club heads and methods to manufacture golf club heads
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having an interior cavity, a front portion, a back portion, a toe portion, a heel portion, a sole portion, and a top portion. A face portion is attached to the front portion to enclose the interior cavity. The golf club head may further include a port on the body portion that is connected to the interior cavity. A first mass portion may be coupled to the body portion such that the port is configured to receive the first mass portion to close the port. A second mass portion may be coupled to the body portion and include a different material than a material of the first mass portion. The maximum width of the interior cavity may be below a horizontal midplane of the body portion and above the port. The interior cavity may be at least partially filled with a filler material from the port. The interior cavity may at least partially extend over the port at a location of the maximum width. Other examples and embodiments may be described and claimed.
