Stock 6.1 hemi rods big and small end weight?

Anyone here every weigh the big and small end of a 6.1 hemi rod or know the approximate weight or each? I found some specs on the 6.4 rods, but they are a little shorter and not sure how close they would be.

As far as I know the rods are all the same length. 6.243
early 5.7 are 597gr 6.1 are 650gr.
As for big end and small end

All the aftermarket 6.4 Rods I see for sale are 6.200 So figured that's the stock length on them. I did find the big/small end weight on oem 6.4 rods are 469 and 189 grams.

If not the rod end weights, anyone know the approx 6.1 hemi bobweight?
