Two years ago I had a set of pistons knurled and the pattern came back with the Perfect Circle logo in the knurl. Knurl then file to fit. Years ago I did that to a Ford industrial V4 in a Saab. Ten years later another local wrench called me up to find out what I'd done to the engine. It needed a valve job, otherwise running strong after another hundred thousand miles.
