Dunno. Why would you want to?
If the pitting is bad enough to affect sealing, you are likely to affect it a whole lot worse by trying to grind it out with a disk.
I'd think you could probably fill pits with one of the gasket sealants from, say, Permatex, though I can't remember having that problem so I don't think I've ever tried it.
Being me, and being here, I'd probably try brake fluid to help clean it, and if I couldn't get sealant I might try aluminium foil and sunflower oil to help seal it. The foil would act as an abrasive and the pits might fill up with oil-bound aluminium slurry.
