I was just copying verbatim what the ARP tech sheet stated, that is what he was asking for. I would agree with calling the machine shop and finding out what you should torque them to.
Yes, these engines stretch and move around when they are fastened together. This why no one should ever bore one of these engines with out using a honing plate to simulate the heads being bolted to the engine. Some people even claim that the main bearing clearance changes when the heads are bolted up to the block. The machine shop and I confirmed that they did not change on my engine before I assembled it. I have .0015 clearances on my main and rod bearings. When I picked my engine components up from the machine shop they had one tag tied to a connecting rod, and one wrapped around one of the main studs. These tags had the torque values they used when performing the machine work. They were the same as what ARP recommended. The machine shop also gave me the small moly lube packets that came with my ARP fasteners.
I am not going to argue how much more or less friction is created by different lubricants. These fasteners have a 190,000 psi yield strength. That has got to be higher than the factory bolts. These are ½ diameter studs they are going to distribute the load way better than the factory bolts with out distorting the block. Engineers use studs and accountants use bolts.
Lets talk about the torque wrench being used to fasten this assembly together. How accurate is it? When was the last time it was calibrated?
I am not going to argue with anyone, I am just going to say I agree with what ARP recommends. I know others will have different opinions, but this is mine.
