That is how I have always done them, no problems.

Using ARP Moly (which I strongly recommend) the specification is 80 lb-ft. This value was revised last January.

Its 80 ft-lbs with moly lube. I did 85 lbs when the specs were 70lbs. I like the extra clamping force. 25 on the small upper studs.

Moly lube is recommended by ARP and the torque specs will change based on if you use it or not.
