Just like the above poster mentioned, final torque is 75 for the large bolts. I did 35,55,75 on mine. The small ones I just snugged up with a ratchet and torqued to 25 ft/lbs.

The sheet that comes with arp bolts says 75 if you use arp's lubes and 85 if you use 10w30 motor oil.

That's very important to note...my father told me a long time ago how he uses different torque specs on bolts depending on which lube he uses on them, and it makes a difference for sure.
