are you trying to put studs in with the heads still on?


the way to do it is remove the head, install the studs hand tight/snug. no real torque.

the torque on the threads comes when you put the nut on after the head is dropped onto the studs, and you torque the nut on the stud. it will pull up on the stud as you torque down on the nut, and the threads will seal. (as long as you also put some light sealant on the threads for the wet holes)
