ever dimple the intake runners?, piston tops? do these give better mileage, performance?

I wouldn`t think so. Dimpling the piston tops maybe effective in creating more swirl if a tight quench is used, but other than that, there`s no real reason to do it. dimpling the intake runner would be somewhat doing the same thing, but all the casting flash already in stock and aftermarket intakes does it for you.
