I presume you meant .030 over! Even if millimeters, 30 is a lot. As for the planing of the head and block, be sure your valves still clear the head (there is much about that elsewhere on this site) but milling the head is rarely needed unless it has actual dents or severe dips in it. It's thin and flexible enough to pull down easily when torqued.
