Nevermind, did a Google search and found this:
Are you using arp moly lube?
If so use this:
First pass 25lbft second pass at 50lbft, and finally a 3rd at 70lbft.
Finally install the 5 smaller ARP bolts and torque them to 22lbft.
If using motor oil use this:
First pass 30lbft second pass at 60lbft, and finally a 3rd at 80lbft.
Finally install the 5 smaller ARP bolts and torque them to 28lbft.
(Incase you didn't know you have to lube the threads and washers before installing... you must use either arp lube or motor oil. )

vettenuts will probably chime in with better info when he sees this, but I believe ARP upped the values to 80# a year or so ago.
I tq'd mine to 75# (before their revision) and all has been well.

make sure the beveled part of the washer faces nut!
edit - nm thought u had bolts - arp told me for studs washer orientation doesn't batter, only bolt that it matters
