    ARP Bolt/Stud torque specs?

    What torque down numbers/specs are you guys using when switching to ARP hardware? Since they aren't stretch bolts, I can't really go by the service manual. I was hoping someone could help me out with what to torque the ARP head studs & rockers bolts down to? Thanks.

    The Way I do is factory spect is 29.5 lbf +120 degree +90 degree
    I do 35 to 40 and then 120 degree +90 degree

    Seems like that would over torque them, but I'll do it! Thanks!

    Arp torque specs:
    apply arp moly lube to the top threads of the studs, washers, and the 12 point nuts.

    Torque first to 45ft/lbs first in a crisscross pattern starting from the middle of the head working your way out
    Re-torque to 65ft/lbs
    Then re-torque to 75-80ft/lbs

    You r done,

    i went 45,55,75 myself........one other thing u best check is the ARP studs sometimes hit the valve cover and wont let the valve cover seat and seal.......i use grease on the tops of the studs then set the cover and see where it touches.......then use a die grinder to remove the necessary amount up inside the cover to let it seal......its been by the number three cylinder end top and bottom...look good or u get a leaker!
