Default ARP rod bolt markings

Do ARP con rods bolts have any special markings on them to identify them as such. I was told my rods have ARP bolts but want to be sure and I'll do them now as the sump is off if not.

Also if you fit ned rod bolts do you need to fit new big end bearings or just do them one at a time, old off, arp on, old off etc..

Yes they should have ARP on the end face and also they are not hexagonal, they look simular to the pattern found in sockets without the flats on.
If you have gone to the effort to change the rod bolts i would personally change them one by one. bolts out,bearings out, new bearings in, ARPs in.

They are a Torx socket 12 IIRC (could have been T20 not sure) so should stand out a mile, ford ones are a 13mm Hex.

yeah these are torx ends, but don't have ARP on them which made me curious. They must be ARP's then.
