A golf club head incorporating at least one interior port adapted to receive a weighted rod which is introduced into the head and the port through an opening and cavity defined in the hosel junction. The weight and density of the rod determines the location of the head center of gravity. In one embodiment, the head includes two elongate arcuate ports adapted to receive respective elongate flexible rods adapted to conform to the shape of the port. An associated tuning package allows an individual to identify and select a recommended rod combination depending upon the desired weight and center of gravity location.
