Good luck. I have not had much luck with the "We will scan it and put a good match in a can for you" deals. Plus, make absolutely sure they are selling you a spray paint for an engine!!! Would you paint your engine with Krylon or Rustoleum? No, you wouldn't. Krylon and Rustoleum are great for a lot of things, but not for an engine. Make sure the body shop is actually selling you a paint that is for engines. If the match is not perfect, Spray the manifold and the valve covers. That will make things blend better.
