    specs are for a 2.6L engine 4ZE1, 1991 Isuzu Pickup


    Sequence

    7 3 1 5 9
    8 4 2 6 10


    Torque

    First Stage 57.8 ft lbs

    Second Stage 72.3 ft lbs


    Ideally you would use new heads bolts if you can find them.

    Re-torquing shouldn't be necessary but all engines are different so you might need to consult a factory workshop manual or perhaps re-check the headbolts in 1000 miles or so.
