5.3 PTV Clearance

I was wondering if anyone out there could help me with some PTV clearance guess work. I'm building a 5.3 with 4.8 flat tops, using the 862 casting head shaved down .035 with the larger 2.00 inch valve installed. The cam I want to use has .610/.617 lift, 223/231 duration at .050 and a line seperation of 112 degrees. Am I going to hit? If so how deep of reliefs do I need in the Pistons?
