There is no need to go to the extreme of spray metallizing to return the head to exact original thickness, .010 will not cause the valves to hit the head it will only raise the compression ratio a tiny bit and result in better performance.
Valid statement if the head has never been worked on but unless you are the original owner you can never be sure someone else has not done the same thing before.
IMO, it is always a good idea to do the clay test on any unknown head before considering removing any material. Before so you don't waste time and money if it is already too close to the valves and after in case the shop took off more than they had planned. As several have found the hard way, the extra time spent would have saved a lot of aggravation and money.
