Which ARP part number is the correct one for head studs for Performer heads. I think it is ARP #154-4005 but am not 100% sure. According to the install instructions the correct head bolts to use without having to use bushings is ARP#254-3708 but I want to use studs because I will eventually put a bottle on it. So if someone could confirm or give me the correct number I might be able to get the motor back together and the car running again soon.
