You want the bad-ass stuff that is not safe for all finishes. You want to cut into the aluminum and remove anything that is stuck to it.
Of course if you are in California, it probably is banned there.
When you spray it you can really smell the acid in it.
This should work well enough so that you do not need to media blast.
Very often when you blast, the media blasts in impuraties into the aluminum and in addition to the blasting, you need to "wash" it.
Personally I wouldn't clear coat anything. The clear coat is a paint and at some time in the future it is going to peel and chip making cleaning it in the future more of a chore.
Just leave it alone.

One of the nice things about a Cleveland is there is no coolant in the intake. This makes pulling off the manifold very convienient.
When I was showing I'd pull it off on Saturday morning to do a afternoon show.
