I have the same setup too, I used ARP lubricant an torqued mine to 35 pounds, just make sure you don't bottom out the stud before you torque the nut, because it will eventually jack the helicoil out, I found out the hard way. Just screw the stud in all the way an then back it out 2 or 3 turns then torque. Thats the way I do it Good luck
