Engine Compartment 1964 Daytona HT

I recently purchased a Daytona HT. The engine and engine compartment needs to be cleaned and the engine repainted or partially repainted (top side). I would like to know the best way to tackle this without pulling the engine. I know many of you are experts in this area. Any tips on cleaning and the way to re-paint (especially in the hard to reach places) without getting paint on areas you aren't painting (at that moment) will be appreciated. The car has AC and PS.
