Thats what I'm saying. They look flawless for bearings that have been in a running motor...especially a motor with no oil pressureDid you pull those bearings fresh out of the ACL box and take a picture?

Google image ACL race bearings. Yours look brand new man. If oil starvation happened those bearings would be showing copper. It still has the damn coating for christ sakes.
eh... no. Just use a thicker OEM bearing. No need to machine anything. Plus "lapping" is the wrong term there.
Nick is right. If heat discolor was from oil starvation then youd need friction which causes scratches/polishing and you have none. The discoloring you have is just the coating ACL uses on their race bearings. They look flawless.
why did you need a race bearing in the first place?
Also ACL was bought by a chinese company recently, and they state that the race bearings are still made in the US but they arent, theyre made in china.
