Head Studs
ARP 2000 Head studs are recommended and are covered in a separate article. They are the same stud kit for any 6.2/6.5 or P400
Main Studs
The main studs for a P400 girdle follow the same torques spec for our 10mm outer main stud 6.5L #506 block kits. The studs are just longer for the P400 to accommodate the girdle.
