2.02 or 2.055 valve?

Im running a 360 stock stroke, rods, 10.5:1 pistons. RHS heads. Mainly race with a little street. First ? would you leave it the 1.92 or go bigger. 2nd ? is would you go to a 2.02 or 2.055 (price would be the same). My machinist is charging me $40 to cut for bigger valves and would be 140 for a 3 angle 190 for multi angle. 3rd question is it worth the 50 bucks for a multi over the 3 valve? and info would be greatly appreciated. thanks
