ARP stud and nut kit is 120 lbft and i your using an early cometic gasket these had a problem as i was informed late last week as mine also went
The centre firing rings were 4 thou thicker than the outer to increase pressure around the combustion chamber but left the rest of the gasket not clamped down fully they have now sorted this.

std bolts are fine to use also as long as there torque to spec:

stage 1 25 to 25 nm
stage 2 45 to 50 nm
stage 3 rotate futher 170 to 180 degrees
