A wire wheel brush will not damage a cast iron block. Most mechanics shops will use a die grinder with a wire wheel attached. This wont damage a cast iron block, yes it'll harm an aluminum block or other aluminum pieces but you'd have to sit there for hours and wear that wire wheel to nothing in order to hurt cast iron. And yes, I'm speaking from experience. I've been a technician for 5 years now and done my share of this type of work. A die grinder with a wire wheel attachment is by far the fastest and easiest method for removing head gasket material. Also, just as mxexux stated, you can also clean the piston tops with it as well, it won't harm them either.
