The easiest way is to use a good primer, and to use high heat paint from a spray can..
If you want to paint it base/clear, make sure you wash the engine properly (I like to use Castrol Super Clean), put like 4 coats of primer, 2-3 coats of base, and 3-4 coats of clear.. ..oh yeah and use a good high-heat primer..
