milled heads

With that cam you will have plenty of valve to piston clearence even with .050 milled off the heads.
You can only mill .030 safely with stock pushrods as the lifter only has about .060 travel total and the pushrods should be in the middle of travel or close. So my suggestion would be to run a fully adjustable velvetrain and eleviate this problem. Also keep in mind that when you mill this much off the deck surface of the heads that you will also have to mill .012 off the intake face of the head so to keep the intake geometery right for every .010 off the deck of the head.
