Pump gas compression again

When my rods showed up, they had bolts that said ARP on them. I know the Chinese are knocking this stuff off so I called ARP and told them who made the rods and who imported them and asked if he knew if they are real ARP stuff. And he said they were a quantity buyer and they are ARP bolts. So I sized the rods for clearance and bolted them in.
Mine don't say arp & don't have a do not on the other end for measuring torque stretch
