i would say if your going to dis assemble the engine and rebuild it- any automotive machicine shop can dip the engine and heads and that will clean off all the gunk..
but if your not going to take it apart, i would say just scrap off all the crap, and then wire brush it really well, then paint it..
as far as what kind of paint to use, i use the engine paint that u buy at autozone, and it has never chipped of or anything for me
