What rings and what bearings?
 

What pistons rings should I get with for rebuild and what bearings?

I would use Clevitte 77.... The H bearings. They're more expensive, but are an extremely high quality bearing.
Rings, I'd get Plasma moly file fit rings. I've heard alot of pro's and cons about the gapless rings and no cons on the plasma moly. Just remember, with plasma moly rings, the cylinder bore needs to be extremely smooth, but your engine builder should know that.
