"Tighten the manifold-to-head nuts. Start at the center and work outward to snug, then go back and torque the three intake-to-exhaust bolts to 22 foot pounds. Now go back and torque the head fasteners to 10-12 foot pounds of torque, again from the center outward." And I agree, I used inch lb torque wrench for the same reason :thumbsup:
