I'm getting adeal on some powder coating (another company is doing a bunch of stuff in red, and there is leftover space).  I was just going to do my valve cover and strut bar, but since any other stuff would be free, I might as well do more.

Sooo....
what else can be done without side effects?

Brake Calipers

Intake Manifold

how long would it take to remove my valve cover and intake mainfold?

Would an hour be enough?
I'm trying to minimize the time that the parts will be gone.
