ARP Torque Specs?

Re: ARP Torque Specs?
i dont understand how people have the headstuds and the information to get the job done and still need to make a post. if arp says to go to a certain spec follow manufacters recommendations. 10lbs is not much and can be ran on stock headbolts. if arp says to go less with lube its simply because the lube reduces the friction and will give a lower torque reading. on any fastener, most of the torque being applied to the bolt or stud is overcoming the friction between the threads, the rest is bringing the bolt to its maximum stretch limit. just install the headstuds and torque them in steps in sequence. arp may specify different specs for a dry torque or a lubricated torque. i used the moly lube and torqued to 60 ft lbs and had boost spikes to 15lbs and never have a problem at all.

As always this board shows its high level of knowledge, thanks all. I will call ARP Monday AM to get the specs, and will torque accordingly.
