That was the Aztecs, wasn't it? As far as I know, although the Inca's and Mayas practiced a form of human sacrifice by burying groups of people alive with their deceased royalty, they didn't do the really brutal stuff that you are suggesting. I could be wrong, so if you have any information which can enlighten me, I will be happy to read it.
If you'd tried to do that to the Inca he'd had you chopped into little pieces.
