I’ve got issues with stock head studs and decided to keep on with arp2000 series, but there wasn’t any instructions in the package as to how many torsions must be tightened. Should I back to stock ones as they’ve got exact torsion info? I’m gonna hit 29 psi at best. I’m expecting precise informations from people who have enough clearance, please. Any help would be greatly appreciated.
