Hi martsink,
well, the common way if you must overbore the cylinders is to use steel sleeves. There are a very few engine builders over here in Germany that offer overbores in combination with a new Nikasil or nickel / ceramic coating. It's not a very common solution, but it's possible and it is much more expensive than steel sleeves. That is why most people prefer the steel sleeves. Problem with the steel sleeves seems to be that they loose the hone pattern over time. Also if you use steel sleeves you also should use forged pistons, because of the thermal expansion. So there are pros and cons.
