I have had engine builders do exactly that on bearings WHEN they know there is a issue!Most ASSUME if bearing clearance is proper they dont HAVE to do something to brand new bearings!It seems like something has changed on Clevite 3 1/4 main bearings compared to other brands.The set Mike has in his shop also dont have the little half moon cut outs on the #4 bearing?The rep looked at them and was at a loss as the box said maid in the USA.Inquiring minds need to know!Tom
