After searching here and MSV i've found a couple people saying to torque arp studs in the OEM sequence up to 110 lb/ft... but also a couple mentioning the 85 lb/ft that arp states.... Which is correct?? I would assume 110 but just checking to see what others have done that works...

i bought them from summit racing, cheaper.
ARP 251-4701 - ARP Pro Series Cylinder Head Stud Kits - Overview - SummitRacing.com

Hate to bring an old topic alive... but BUMPPPPPPP... I just snapped FEL-PRO bolts putting them in, need something better. I was torquing to 95ft/lbs when it popped.

Thanks

Thanks, you guys are fricken awesome! I was actually wondering about the torque specs.

Do we use the 90lbs stated in the instructions? or do we torque down to the FSM 110lbs?
