How to remove and replace the exhaust manifold on the right side for 4.8L, 5.3L, and 6.0L engines on Chevrolet Silverado 3500?

The procedure for Exhaust Manifold replacement on the right side of 4.8l, 5.3l, and 6.0l engines demands that you begin by raising and supporting the vehicle before uninstalling the Exhaust Manifold pipe nuts. First lower the vehicle and then eliminate the spark plugs before disassembling the Exhaust Manifold bolts and manifold pieces while discarding the old gasket. The Exhaust Manifold heat shield needs to be separated from the manifold by removing its bolts and shield components along with it. Refurbish the Exhaust Manifold first before securing the heat shield to it along with the bolts then fasten the bolts to 9 nm (80 inch lbs.). The threads of the Exhaust Manifold bolts require a 5 mm (0.2 inch) wide strip of threadlock gm p/n 12345493 (Canadian P/N 10953488) or similar product whose application must occur after clearing the clean threads of debris from the cylinder head Exhaust Manifold bolt hole areas. Fasten the Exhaust Manifold along with its new gasket and bolts by first tightening their center points to 15 nm (11 ft. Lbs.) then moving to opposite bolts until reaching the outer bolts. After this initial phase complete an additional tightening to 25 nm (18 ft. Lbs.) following the same bolt pattern. Create a bend on the exposed gasket edges of the Exhaust Manifold at the front right cylinder head using a flat punch before installing spark plugs. The vehicle increases in height to install Exhaust Manifold pipe nuts while tightening them to 50 nm (37 ft. Lbs.) before proceeding with lowering the vehicle.
