i don't see how that could hurt anything. might actually help against detonation because your getting rid of any deposits on the piston

I would scuff them to help form a nice carbon layer that will help to insulate the piston domes.

Polished surfaces could lead to hot pieces of carbon flaking off and leading to detonation, or worse.
