I heard you, about the 2000 vs 5000. When you do get them in front of you. You will be able to tell if they are the Arp 2000 as they are stamped on the head of the bolt, at least mine are.

I also should state that the torqueing instruction specs wasnt Directly from ARP. They were from 440Source. It looks like they retyped ARPs original instructions for the ARP2000 bolts that were supplied withy thier Hbeam rods. So there is a possibilty of a Misprint Typo.

I have not installed mine yet so I better check with ARP myself. mike
