What brand? RJC uses quality ARP studs, and grade-8 pan rail studs. CAT.....not sure what they use. ARP studs S/B torqued to 90ft./lbs WITH ARP lube on the threads and washers. The pan rails nuts torque to 25 ft.lbs. Do you have the proper set-up instructions? If not, be VERY careful on how you set it all up. Do NOT cut corners on the set-up. The machine work is CRITICAL. All the bolts MUST be torqued at full value prior to line hone. There needs to be a .005" gap between girdle and pan rail. Please tell us that you had the machine work finished previously and lost the instructions. Not a job to do with out detailed instructions.
As an edit to the above torque of 100 ft. lbs. IF you torque a fine threaded nut, then you "should" reduce the torque by 10%, especially with a stud and nut. (with ARP lube) BUT if your machine shop torqued the studs to 100 when they line honed the block, then use the 100 ft. lb torque.
