Arp cam gear bolt torque spec

Does anyone know the torque spec for the arp cam gear bolt? I installed months ago and can't remember the spec now that I'm back into my engine for a headgasket and rmw cam.

I'm pretty sure the paper that came with my arp bolt said over 100. But arp hasn't gotten back to me and I can't find the paper!

Do a "ModMini head gasket replacement" on youtube. In the second part you will see him doing the upper bolt.

I've seen that, but he uses the OEM bolt. Almost ALL arp hardware is torqued tighter than oem

Go to the ARP page, find the kit number and they have a page where based upon the diameter of the bolt they list the torque value.
