Golf club heads and methods to manufacture golf club heads
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 may include a body portion having an interior cavity, a face portion enclosing the interior cavity, a first mass portion and a second mass portion coupled to the body portion, a port connected to the interior cavity, and a filler material injected into the interior cavity from the port. The second mass portion includes a top portion and a bottom portion oriented relative to each other at an angle at least partially corresponding to a contour of a portion of the toe portion edge. The mass of the top portion of the second mass portion is less than the mass of the bottom portion of the second mass portion. Other examples and embodiments may be described and claimed.

a hollow body portion comprising a toe portion with a toe portion edge, a heel portion with a heel portion edge, a front portion, a back portion with a back wall portion, a top portion with a top portion edge, and a sole portion with a sole portion edge;
a face portion coupled to the hollow body portion to define a closed interior cavity in the hollow body portion, the face portion comprising a front surface having a plurality of grooves, and a back surface comprising a toe-side groove portion extending in a top-to-sole direction, a heel-side groove portion extending in a top-to-sole direction, and a top-side groove portion extending in a heel-to-toe direction;
a filler material in an interior cavity of the hollow body portion;
an external mass portion;
an internal mass portion;
a first port below a horizontal midplane of the hollow body portion; and
a second port inside the interior cavity, the second port having a different shape than the first port;
wherein a distance between the second port and the heel portion edge is greater than a distance between the first port and the heel portion edge,
wherein the first port is configured to receive the external mass portion, and
wherein the second port is configured to receive the internal mass portion.
9. A golf club head as defined in claim 8 , wherein the toe-side groove portion, the heel-side groove portion, and the top-side groove portion are connected to define a continuous groove on the back surface of the face portion.
10. A golf club head as defined in claim 8 , wherein the toe-side groove portion, the heel-side groove portion, and the top-side groove portion are connected to define a continuous groove on the back surface of the face portion, wherein end portions of the toe-side groove portion and the heel-side groove portion have a circular or elliptical shape.
11. A golf club head as defined in claim 8 further comprising a second port connected to the interior cavity, wherein the filler material is injected into the interior cavity from the second port.
12. A golf club head as defined in claim 8 , wherein a mass of the internal mass portion increases in a top-to-sole direction.
13. A golf club head as defined in claim 8 , wherein a shape of the internal mass portion is configured to at least partially correspond to a shape of a portion of the toe portion edge.
14. A golf club head as defined in claim 8 , wherein the external mass portion defines a visible portion of a center portion of the back wall portion below the horizontal midplane.
15. A golf club comprising:
a shaft having a first end and a second end;
a grip coupled to the first end; and
a golf club head coupled to the second end, the golf club head comprising:
a body portion comprising a first material having a first density and being hollow to define an interior cavity, the body portion comprising a toe portion with a toe portion edge, a heel portion with a heel portion edge, a front portion, a back portion with a back wall portion, a top portion with a top portion edge, and a sole portion with a sole portion edge;
a face portion coupled to the front portion to enclose the interior cavity;
a first mass portion coupled to the body portion and comprising a material having a second density different from the first density;
a second mass portion coupled to the body portion and comprising a material having a third density different from the first density;
