Yep, book says 100.
But if you do that to the factory once for too long, you'll most likely snap one.
I used 85-90 on the factorys because with 100, as the lug nut turned, I couldn't feel increased resistance--not good.
So I joined the ARP stud crowd, and use 100 ft/lb with no issues.
If you track the Boss, get ARP studs, and don't look back.
