It is reasonable to expect exhaust deposits and corrosion because exhaust gases pass thru the intake manifold. If it is real heavy deposits or signifcantly plugged then clean it out. Probably plugged or heavy deposits due to alot of stopping and starting of engine, short runs, city driving etc over the years.
