Use 220 dry to get out all of the casting marks/imperfections.
400 wet to get out the scratches from the 220.
600 wet to get out the scratches from the 400. The piece should have a low luster at this point.
Go to Lowe's and get the polishing compound in the plastic tubes. I would recommend 1,2, &4. You need a different yellow (hard) wheel for each of the #1 & #2 compounds. Don't mix wheels. White (soft) wheel for the last compound.
Prepare to spend 40 hours or more on a perfect piece. Do it right and it will look similar to below.

40 hours! Now I'm demotivated to even try lol.
I wanna do my intake pipes and manifold and alternator and tstat housing. shouldn't a drill with the sand paper mounted make it shorter?

In that case just 1/2 *** the sanding up to 600 grit and use some Mothers Mag and Aluminum polish.

An alternative you might want to try is glass beads under lower air pressure it produces a satin type of finish looks nice and clean , we do a lot of motorcycle heads and so on that way .
The intake you could clear coat after I don't think there is enough heat to bother . just make sure you mask off all gasket surfaces and blow the hell out of it with air to make sure all the beads are out before installing . The thermo housing would be simple to do . The only real down side is the beads get in EVERYTHING and parts need to be cleaned thoroughly before installation . The alternator would need to be totally disassembled including replacing bearings .. IMO polishing looks great for a while but soon begins to tarnish again just from air exposure if nothing else .
It's a lot of work but the end result is super .

thanks for that, sounds like more work then i thought
what if i just did a certain amount of sanding, not to get a shine, but enough to put on a nice paint job, so that i dont have to worry about the shinyness anymore
since it does go away quickly, and you can just repaint if the paint gets old
is that all safe to assume?
