As others have said stock bearings are fine, pick your favorite brand.
I had a hard time believing it until a friend of mine who runs a late-model car on asphault had a 358ci chevy apart. He runs them multiple seasons (usually) as long as their within his accepted tolerances. He turns that engine up to 7,200 and only looses 800 rpm or less in the turns. Oil temps regularly 240- 260 degrees for 50 laps. He competes in up to 25 races a year depending on funding. If regular Clevites are good enough for him, they are way more than adequate for me.
