More Info:
Today’s critical head studs and bolts, main studs and bolts, and driveline have been designed stronger than ever before to handle the extreme loads. As a result, installation pre-loads, the amount the fastener is stretched during installation, are very high.

There are a lot of opinions out there about which fastener assembly lube to use and what the torque value should be. First, let’s be clear: ARP provides torque specs for their fasteners based on using ARP Ultra-Torque. If you’re not using ARP specs and ARP lube, you have no real idea what pre-load you’re getting. ARP has done the testing where they can measure the torque applied and the resulting pre-loads. They’ve tested with ARP lube and the lube others use… and ARP has the results to back it up.
