If you brake that down into michrometer language,
you have pistons that are one hundred thousands or one tenth of an inch larger than stock. I haven't seen pistons larger than eighty thousands
of an inch over size and that was years ago. You would have some very thin cylinder walls bored a hundred thousands. I may be wrong, but something just don't sound right. One marked 0.20 would be two hundred thousands of an inch or nearly a quarter of an inch. By then you would probably bore into the water jacket. I'm not always right, but then, I'm not always wrong.
