Yeah, ARP's head-torque recommendation varies depending upon whether you're using motor-oil or their special lube on threads. My friend @ Lucas Aviation in S.B. says no bolt ever goes on planes dry, it always has lube, anti-seize or locking compound.
From the manual, I guess you have to be careful with what they specify:

"In these illustrations you will find the
instructions indicating which parts require spec-
ified tightening torque, oil, grease or a locking
agent during assembly."
