I don't imagine it would require flycutting since the LS6 heads have stock valves and the G5X3 works fine on stock heads. However, TSP has a new cam out designed for the LS6 heads they have. I believe they can bump up the compression on them as well. In a 6.0L goat I believe the H/C numbers were 450+hp and 400+tq.
