Would this housing be useable? There's a lot of rust inside and around the end where the hose attaches. It's not soft or holey but rough. Of course I will be installing a new thermostat. The intake manifold also has rust inside that I can't seem to be able to reach. Any ideas?

I still say based on my 50+ years of restoring old cars that the best, easiest and cheapest way of removing surface rust on ferrous metals is by using muriatic acid.   Yes, be careful to avoid breathing the fumes and use it only outside.   Use heavy rubber gloves on your hands.  Leave the parts in the solution only long enough to remove the rust.  Quickly neutralize the acid on the cleaned parts with a fresh water bath.   When done, pour the used acid back into the container using a funnel and make sure not to spill any.  The used  acid can be used over and over.   When the used acid eventually looses its strength, dispose of it as you would any hazardous waste.

Ok but how do I clean the water jackets? Like internally.
