What does '.50mm Oversized' mean for these rod bearings?

This means the bearings are manufactured to be 0.50mm smaller in diameter than a standard-sized bearing. This is used when the crankshaft journals have been machined down by 0.50mm to ensure the correct oil clearance for engine operation.

Are these bearings suitable for a stock engine rebuild?

These are performance rod bearings, designed with tighter tolerances for built engines. While they can be used in a stock rebuild if the crankshaft journals have been machined to the correct undersize, they are primarily intended for performance applications.
