Advancing the cam requires deeper valve cut outs, it $$$tarts to add up pretty fast.
Yes I've looked up most set ups and most of them operate by oil pressure, I was making a set up that worked of off centrifugal forces, it would start off at around 105 deg intake cam centerline ( I can't go any lower or the valve would hit the piston), and around 10k rpm would start retarding to around 111 deg cam centerline.
