piston identification

I am curios if the numbers stamped on the top of this piston indicates that it is an over sized piston and if so what size rings I need for it. And is it an indication that my cylinders have been previously bored. The 0.030 is what caught my eye. Any help would be greatly appreciated. (sorry about the size)

More than likely, yes. Its been like that long as I can remember, they always put the oversize on the pistons no matter what kind of engine. If you want to know for sure, measure with a caliper.
