Exhaust Manifold Cleanup

[57 Healey <57healey@gmail.com>]

Since the Longbridge exhaust manifolds are made of unobtainium, I need
to be sure that the set for my car last a long time.  Any suggestions
for the best way to clean them and paint or coat them for long term
durability?

I still love that the factory stamped the engine firing order on these
manifolds.  No one can read the text is under the carbs and heat
shield when mounted on the car.
