a port above the second mass portion and connected to the interior cavity, the port having a threaded port wall configured to engage a threaded outer wall portion of the first mass portion to close the port; and
a polymer material injected into the interior cavity from the port,
wherein a distance between the port and the toe portion edge is less than a distance between the port and the hosel portion,
wherein the second mass portion is located on the body portion such that a greater portion of a total mass of the second mass portion is closer to the toe portion edge than the hosel portion,
wherein the first mass portion and the second mass portion are made from a metallic material having a greater density than a material of the body portion, and
wherein a total mass of the second mass portion is greater than or equal to five times a total mass of the first mass portion.
9. A golf club head as defined in claim 8 , wherein at least a portion of the length of the second mass portion extends in the same direction as the sole portion edge, and wherein at least another portion of the second mass portion extends in the same direction as the toe portion edge.
10. A golf club head as defined in claim 8 , wherein a width of the second mass portion is similar along the length of the second mass portion.
11. A golf club head as defined in claim 8 , wherein a distance between the first end of the second mass portion and the horizontal midplane is less than a distance between the second end of the second mass portion and the horizontal midplane.
12. A golf club head as defined in claim 8 , wherein the back wall portion of the body portion includes a port having a shape configured to receive the second mass portion, and wherein the second mass portion is bonded in the port with a bonding agent.
13. A golf club head as defined in claim 8 , wherein an outer surface of the second mass portion defines an outer surface of the back wall portion.
14. A golf club head comprising:
a body portion having a front portion, a toe portion with a toe portion edge, a heel portion with a hosel portion, a back portion with a back wall portion, a top portion with a top portion edge, a sole portion with a sole portion edge, and an interior cavity;
a face portion coupled to the front portion to close the interior cavity;
