Bearings and races in SBP Hub

I've managed to obtain a pair of NOS SBP KH rotor/hub assemblies. I see that the hubs already have pre-installed races; however, no bearings. I've always heard that one is supposed to use the matched set bearing/races as sold in parts stores. Any problems in using just the brand new bearings from these sets in the brand new races in the hubs?
