I have been assembling my engine with all ARP hardware. Using there stuff for the heads, rods, main caps, etc. this weekend i will check and do the final tq on my main caps and rods. since i am using ARP stuff do i go by there tq specs or do i use the stock tq specs ?

first are they bolts or studs. Also you go by arp's specs. Their specs are for there bolts(ie to get the proper strech). You can find all their torque specs on their web page. There is two methods. One torque spec with oil and the other with ARP moly lube.

Here is the page.

That brings up an interesting question. Normally the torque specs for ARP bolts\studs using ARP moly are less than with oil as you get the same amount of bolt stretch with less torque. So far so good. Now lets say you run the engine a couple of hours and then want to retorque the heads. Is the slippery stuff still under the washers and you use the ARP values or is it gone and you use the OEM/oil values?
