Zeroing in on valve guide clearance

Got some carbide sizing balls that come in .0005 increments from Goodson's. The ball broaches on a stick came in .001 increments an I wanted to get closer than that. I'm shooting for .001 on intake and .0025 on exhaust. The stems on the exhaust valves are .0005 smaller than the intakes and that is normal.
Ball ready to be driven through.
