If you check BDAG, a well respected Greek lexicon, you will find that “kephale” never means “source” and has not been accepted as being so though out church history (including and especially when the church was chuck full of native Greek speakers who would know).

Furthermore the Louw-Nida, another highly respected source indicates that there is not even a word in the same word family in Greek as “kephale” that means “source”.

The whole argument is a rather recent innovation from Dr. Catherine Kroeger who misinterpreted what was said by John Chrysostom.

This article helps to put the issue in perspective:
