On any rod, the clamping force you're aiming for is whatever was used when the the big ends were bored and finish honed, as then you should have a perfectly round surface. That clamping force in turn comes from the bolt torque used when the big ends were fitted up for machining; obviously, lubrication of the thread has some effect on the transfer of bolt torque to clamp force.
Whatever may have been used -I would suspect a drop of oil- I doubt that the expensive ARP lube was used back the machine shop. Personally, I use a Loctite Nutlock type product when I put up big ends, it does act as a mild lubricant till it sets.
BTW, if you really do want to use the ARP lube, PM me your postal address and I'll put you a sachet in the post. I buy a fair few sets of ARP bolts (I never re-use big end bolts) and the carded sets always come with a sachet of the ARP lube.
