Need a little advice with my 360 teardown

Hi Guys
So I’m tearing down my 76 360 which came out of a Cordoba.
I don’t think it’s ever been apart, but there are a few things I haven’t seen, or am unfamiliar with
First off is the thrust bearing caps, they seem to have punch marks around the edges. Is this a normal thing?
Also, it seems that half the connecting rods on the left bank, have a bronze colour to them, while the others don’t.
Also some of the rods seem to have oiling notches on them, the others don’t..
I just want to make sure I’m not missing anything. Should I just get new rods from summit which already have the arp bolts?
This is just a basic street build, I’m going with speed pro H116CP pistons with Edelbrock heads, intake and XE268 cam
Any advice is appreciated
