Now this business of either machine marks on the piston face or smooth might need some clarification .Now of days on automotive stuff it has the machine marks but they weren't always that way .If you look at older designs it was smooth .Certain ones for example hemi domed where smooth .Some like Jahns pistons from years ago shined like a mirror .
With chainsaw engines it went the same way .
So evidently it must be by design because with modern methods on high speed CNC machinery they could come out with a mirror finish if they wanted them to .
In case anybody wonders I've installed and maintained machinery for one piston line at Honda and 4 or 5 at Ford .
