What does the +1.0mm sizing mean for these bearings?

The +1.0mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined undersize by 1.0mm during an engine rebuild. This allows the engine to be rebuilt to its original specifications even after wear or damage to the crankshaft.

What is the advantage of a bimetal aluminum base bearing?

Bimetal bearings, often with an aluminum alloy overlay, offer a good balance of strength, conformability, and embeddability. This construction helps them handle engine loads effectively while maintaining good oil film support and resisting wear.

Does this set include all the main bearings needed for an engine rebuild?

Yes, this is a main bearing set, which typically includes all the necessary main bearings to replace the main bearings in the specified engine. Always refer to the manufacturer's parts list for your specific application to confirm all components needed for your rebuild.
