What are you looking for as for high performance? How much of a rebuild kit also?

You'll probably be able to get a basic rebuild kit and piece together what you rearlly want from there (pistons, cam, etc.).

 

Summitracing has a Federal rebuild kits with bearings in it. I'd go that way but make sure that you get Clevite 77 bearings. There are rotating assemblies that have forged parts but you'll be spending over $1,200 easy. Maybe take a look into PRW, they might have something too.
