A golf club head including a sole, a back and a face, and a plurality of adjuster pins at least two of which are different in weight, degree of insertion and/or diameter, are inserted into the sole of a wood club head or the back of an iron club head at selected positions on an imaginary arcuate line taken on the sole or back of the head. By selecting the number of the adjuster pins, the combination of the adjuster pins and/or position of the adjuster pins, the center of gravity of the head main body can be three dimensionally changed to provide a wide variety of adjustment in weight.
