Check the Timing first. Usually the case is the ignition timing has retarded to the point were combustion is not completed and hot burning fuel is sprayed into the manifold. Then it finishes burning in the manifold cooking it.
Rich/Lean condition will cook other components before the manifold starts to get hot enough to glow after shut down. But he has said there is other problems.
1) Check the Base Timing.
2) Inspect the spark plugs. Read them for color and deposits.
