Default ARP's
If you bought the bolts new they have the specs in the box, if not 75ft/lbs and 25 ft/lbs on the small bolts

The ARPs are three pass in the stock procedure. First pass is 30-35lbs, second is 50-55lbs, and the final pass is 70-75lbs for the big. Little I forget, I'd have to go look it up. But 25 sounds about right.
