Don't know the condition/appearance of your particular car, but i'll tell you what I do. (Hopefully, you know how to turn wrenches.)
I pull the engine to clean, sanitize, detail not only the engine - but the entire engine bay and associated piece parts. I'm in the middle of such a project right now on a '68 convertible. It's therapeutic, believe it or not!! The MCA Rules & Regulations has a section that specifies correct colors for various areas & components. It's a lot of work, but the end result is WELL worth the effort. It's amazing, the number of glitches you'll find when everything is opened up & exposed. As a result of having everything exposed, today I repaired the P/S Control Valve (endcap was cracked), replaced all P/S hoses due to condition (Ford Junk! Only lasted 40 years). Cleaned & painted all the P/S & linkages (Cast Blast paint works well. NPD sell a decent P/S pump Teal paint, but I think it's too dark.) While everything is removed from the engine bay, it's easy to repaint all of the black panels, clean or replace brake lines, etc.
This is dragging on too long. I could write an essay on this project!! Bottom line - if you want your engine the right color - pull it out & do it right. If I can help, let me know - glad to help.
