All non custom bows are tillered for split finger draws.To find the best spot for the nock start with a bare shaft and set the nock a tad to high.Gradually bring it down until you see the nock high flight go away.In some cases you can't quite get rid of it all together but that's ok.Just be sure what high you're seeing is not being caused by the arrow bumping the shelf which also shows as nock high.That said I would suggest getting the brace height dialed in first.Good luck!
