How to properly remove and install the exhaust manifold in V6 engine on 1986 Chevrolet El Camino?

Raise the vehicle and support it on stands, then disconnect the battery ground cable. Remove the crossover pipe (231 cu in) or exhaust pipe (200/229 cu in) and hang it from the frame with wire. Take off the spark plug wires from the spark plugs, marking them with coded tape. Disconnect the EFE pipe (231) and remove the carburetor heat stove pipe on the 200/229 engine. Remove the exhaust manifold bolts and the manifold. Before installing the manifolds, clean all old gasket material from the mating surfaces on the cylinder head and manifold. If a new manifold is to be installed on a 200/229 engine, install the carburetor heat stove pipe from the old manifold. Place the new gasket into position on the cylinder head using a thin film of sealer to secure it in place. Install the manifold and torque-tighten the center bolts first, then the end bolts. Install the remaining components in the reverse order of removal, using a new gasket or packing at the exhaust manifold or crossover pipe flange. Start the engine and check for exhaust leaks.
