Size buildup of manganese phosphate plating on G2 CAST IRON  

++++++

Hello,
My name is Buzz,I work for a precision machining co. in PA.WE have a new job we need some help with. We're machining G2 Cast Iron (hardened & tempered to 250-300 BHN).It is cylindrical in shape (8.5" long x 2.5" O.D. x 1.7500"-1.7510" dia. bore after plating). How much size buildup should we allow for from the manganese phosphate plating to hold the close tolerance bore?
Any help would be greatly appreciated.
Thanks,
