I am not sure that use of the exhaust brake is hard on the exhaust manifold.
Remember, with the throttle closed, ZERO fuel is injected. Zero fuel means zero additional heat. So, if the manifold is hot from a long climb, once you crest the hill, I don't see a problem with the exhaust brake on-- that will slow the cooling rate, but certainly not add to the heating rate.
