:DThere are 2 main tribal groups in Borneo. 1 The Dayaks 2 The Iban.

 Head hunting was outlawed many years ago. I vividly recall my first visit to an Iban Long House. 1st. a drink with the chief. 2nd a little tour;' during the tour I noticed a small hut; looked in and there was a stack of heads . I was indeed pleased to be assured by the chief[ who had NO teeth] that "most of them were Japanese"; I dunno about the rest and he did not elaborate further.VERY INTERESTING FOLK.
