I'll be following with great interest.
I've often considered polishing the surface of the piston as well. I've noticed that stock pistons are typically quite a rough casting on the combustion surface, whereas the rest of the piston is nicely machined. I've also noticed that aftermarket pistons are generally machined on the combustion surface as well as the skirt, etc. This leads me to wonder if there might be two benefits to polishing the combustion surface; one is the theoretical efficiency increase in moving fuel/air and exhaust, and the other is resistance to carbon build-up. What do you think?
