Golf club heads and methods to manufacture golf club heads

A golf club head comprising:

• a hollow body portion having a first interior cavity portion and a face portion, the face portion comprising:
• a front surface;
• a back surface opposite the front surface;
• a face perimeter portion having a perimeter edge defined by a face toe edge, a face heel edge, a face top edge, and a face sole edge;
• a face recess portion on the back surface located within the face perimeter portion;
• a back groove in the face recess portion;
• a ridge portion extending from a portion of the face perimeter portion proximate to the face sole edge into the face recess portion;
• and
• a wall portion coupled to the ridge portion and extending outward from the ridge portion;
• a first filler material;
• and
• a second filler material,
• wherein a volume bound by the face recess portion, the ridge portion, and the wall portion defines a second interior cavity portion,
• wherein the first interior cavity portion is at least partially filled with the first filler material, and
• wherein the second interior cavity portion is at least partially filled with the second filler material.

A golf club head comprising:

• a hollow body portion being including a first interior cavity portion at least partially filled with a first filler material, the hollow body portion having a front portion with a front opening;
• a second filler material;
• a face portion coupled to the front portion to close the front opening, the face portion comprising:
• a front surface;
• a back surface opposite the front surface;
• a face perimeter portion having a perimeter edge defined by a face toe edge, a face heel edge, a face top edge, and a face sole edge;
• a face recess portion on the back surface and having a recess perimeter portion at least partially surrounded by the face perimeter portion;
• and
• a plurality of back groove portions in the face recess portion, the plurality of back groove portions extending proximate to the recess perimeter portion along at least 50% of the recess perimeter portion,
• a ridge portion extending from a portion of the face perimeter portion proximate to the face sole edge into the face recess portion;
• and
• a wall portion coupled to the ridge portion and extending outward from the ridge portion to define a second interior cavity portion in the hollow body portion;
• wherein the second interior cavity portion is at least partially filled with the second filler material, and
• wherein a coefficient of restitution of the first filler material is different from a coefficient of restitution of the second filler material.
