Clevite makes good bearings. King bearings aren't bad, but they are kind of an off the shelf brand. Lots of stroker kits come with them. I'd get the Clevites. Bearings are inexpensive in the scheme of things, and Clevite is a known brand that has been around forever. Pretty sure I have Clevites in my car right now. That being said, the stroker kit originally came with King bearings and they stood up just fine.
