Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a method of manufacturing a golf club head includes forming a body portion with an interior cavity, forming a face portion, attaching the face portion to the body portion to close the interior cavity, injecting a polymer material into the interior cavity from a port on the body portion, and inserting a first mass portion into the port to close the port. The method further includes attaching a second mass portion to the body portion below a horizontal midplane of the body portion. A total mass of the second mass portion may be greater than or equal to five times a total mass of the first mass portion. Other examples and embodiments may be described and claimed.
