I'd get oversized pistons. 81.25mm. This way you can set the pistons to wall clearances to spec and the boring process itself garentees the cylinder walls are true round. Boring costs about $80 or so and is WELL worth it.

I don't believe in taking it real easy on a break in especially in the first couple of miles. Cylinder pressure is what helps the rings seat. The pressure gets behind the ring in the ring land and forces the ring outward which is how they seat by friction with the cylinder wall. Taking it real easy just makes this process last longer. The longer it takes to seat the rings the more friction, created by the texture of the hone, is lost. To each his own, I just wanted to explain my reaoning so no one thinks I'm crazy.
