Getting the accumulated stuff out is important. Some of that crud was also part of the engine at one time. Some other things accumulated too but mostly iron oxides. Not all corrosion is uniform, so you may just have a block that's in bad shape and not much you can do about it except replace. I posted similar remarks several years ago now. You can assess the condition better if torn down for rebuild. Cast iron won't last forever with water based coolant running through it. If it's going to sit, drain and dry it out.
