Last I checked oven cleaner will take carbon off. I'm not sure I'd use it on an aluminun or magnesium engine part though.
 
Scotchbrite pads or rotary discs work well in combination with any good carb cleaner on dissembled parts. 600 or 1000 grit tri mite paper for real stubborn areas, just wash down after completion.
