66fs, as im looking through this pile of rockers im noticing that the round area that the shaft rides on... on some it looks like a perfect circle and on others its a little bit of an egg shape, maybe its not an issue or maybe its an optical illusion lol... there is no galling on these , all look pretty good
Slip them on a shaft to get a better read. It is probably an illusion. They are most likely fine. Hydraulic rockers are only "round" where they interface with the shaft.
