I'll try that and report back.

Get some Purple Power degreaser. Spray on engine wait awhile. Hose off. Very good stuff. Or if you want to be kind to the environment, spray on, wait, wipe with paper towels. Repeat several times then spray again and rinse with hose.

The Eastwood lacquer sounds like a good idea once the parts are clean.
I rubbed the top of the cruise control unit with a Scotchbrite pad and got it down to shiny aluminum, but there's no way to clean it with Scotchbrite or any other abrasive cleaner down in the inaccessible place without taking everything apart. Before EPA there were cleaners that could be sprayed on a hot engine and then blasted off with an ordinary hose. Several treatments like that and the engine looked pretty clean. I looked up steam cleaners on the 'net and found a number of them; mostly for carpet cleaning. The prices range from about $100 to $400.

Has anyone had experience with these light duty steam cleaners? The ones I used in years gone by were very large units heated with kerosene, so I don't know how effective a carpet type steam cleaner would be in the engine compartment.

Have you thought about coating the cad plated bits with a clear satin lacquer? Eastwood sells this stuff. I do it occasionally to parts when I replace them. It actually works pretty well and you can't see it.

Its easy, just take everything apart and clean it piece by piece :-)

I had done a valve job on this car when I bought it and went through
everything carefully.  I replaced lots of little bits, and cleaned
everything as I went along. The valve cover was done with a soft abrasive
wheel of some kind.

That only works on some parts of the country, unless you have temp/humidity controlled garages. In many parts of the country, cold air is replaced frequently by warm moist air. This causes condensation on metal parts that are still cold. This leads to the cad plating (Bright) being eaten away, leaving some oxidized zinc (dull) on steel parts. Cars I have bought from warm dry climates with shiny cad plating turn dull in just one winter exposed to this kind of weather. Even cars stored in unheated garages have this happen. It is accelerated by salt on roads, but it happens to cars in storage too.
