ive heard many different torque specs and people seem to be torqing down to 250 so they dont have to go back into the motor to re torque as per specs by arp
anyone running the a1 head studs ive been hearing not so good things about the entry level arp and i cant justify 1200 for the custom age studs :pullover::fordoval:
