so i am doing a minor rebuild in my new zenki and i was thinking of polishing the pistons for when i turbo it. has anyone done this? seems like it would reduce carbon build up. and i know when people go all out on heads they polish the combustion chamber of the head. so anyone have factual information? thanks
