Question using NASCAR SB narrow rod bearing CB481HN?

Just spoke with my custom rod manufacturer who told me he machined the bearing tab slots differently in the upper and lower parts (rod and cap) of my connecting rods. The reason being the sample connecting rod bearing I sent him had the tab offset a little differently between the two halves. At least, that is what I understood from the conversation a few minutes ago.

Now that to me sounds extremely odd/strange/disconcerting. I hope he did not screw up the orientation of the rod bearings somehow. The reason for using this narrower NASCAR rod bearing (CB481HN) is to accommodate a crankshaft with full radius fillets. Anyone have experience with this Mopar small block connecting rod bearing and/or the full radius crankshafts? This is all new for me. The project I am working on is a de-stroked 340 to 305 by way of a 2.96" stroke crankshaft replacing the standard 3.31" crankshaft. Thank you.
