Head Bolt Set Operation:
Certain modern engines have a changed head bolt design, but use the general procedures for tightening on specific engine models. Torque to yield head bolts must be discarded after use, making them as disposable as the head gasket itself. Some "head" or "full" set gasket packages contain the head bolt sets. The final torque sequence may be in degrees instead of foot pounds, requiring you to purchasing a small degree wheel for your ratchet or torque wrench.
