help me pick cam re-grind for magnum 360

I deal with company's that grind cams that win races and live,not someone that tries to copy what a real cam guy can do. You will not catch a real cam company changing the LSA of a cast(or even a billet ) core very much as the heat treat depth is important if you want a cam that will live. Funny thing is I've seen plenty of stock magnum cams with the heat treated surface flaking off(Not as often as GM hyd rollers) but still should make a guy think about things,if that's an option.
