A good tip to follow when buying heads for a muscle body or sculptors wanting to make a head for a muscle body. If a penny can fit into the neck of a head. It will fit onto any muscle body especially the very muscular ones. Penny's measure 7/8" accross.
if it fails this test for width it's not going on a kaustik,ht tt20 or any other muscle body. the depth of hole should be length of peg and just alittle more to set on neck. the best way to understand depth is to measure. the peg on end of attached neck. it should be that length plus 1/4". most pegs are 1/2" long so your looking at the same measurement of 7/8" for depth
For metric users 22.225mm in depth inside head and width of neck
