Could buy a can of "Gasket remover" spray it on per the destructions then peel it off, I just use a razor sharp scraper carefully.

Best is to have a scraper that has replaceable razor blades so if it gets any nicks or scratches you can throw a new blade on it.

If you have a heat gun, that will sometimes loosen the bond.
(Warning, using your girlfriend's hair drier will cause major bedroom problems)
But a good gasket scraper is also required, and you won't nick the aluminum if your carefull.

If you scratch the surface. You can lap the entire surface by placing emery paper on a sheet of glass. I have removed a baked on gasket before by milling that surface on the same mill I use for the cylinder head. If you damage it enough, you could always send it over to a machine shop to have the surface trued again.
