8 bolts, first pass starting from center and tightening in an "X" pattern tighten to 27 inch pound, second pass 106 inch pound, third pass 11 ft/lb. upper intake manifold bolts 44 inch pound, then second pass 80 inch pound.
there are 10 bolts on upper intake manifold not 8, I need the correct specs and sequence if possible a diagram of torque sequence please. Are the above specs correct just 10 bolts instead of 8, if so I thank you very much for your time. Please let me know.
