Can I replace crank/rod bearings without machine polish/grind?

Need feedback on main & rod journals. Polish/grind? They measure within the factory service limits but I would like to know if the bearings need to be replaced or if the crank needs machining.

Yes, you can replace them without grinding providing the journals are in good shape. You need to a plastic gauge each one and it must be within factory specs.

Are these clearance readings on the bearings? If they are, they look good
