You guys were gracious enough when I first asked this question to offer many great suggestions. I thought I would show what I decided to use for the engine color paint on my 66 big block. I thought some might find it interesting that we found the 69 Hugger Orange color matched almost spot on with my bracket which is an early take off survivor, original paint, smog bracket(you can see the bracket before I stripped it sitting on top of the intake). My friend that owns a body shop came over to shoot it for me. He uses Glasurit paint at his shop. I decided to not go with a complete exhaust manifold overspray, even though I do agree that is how it was originally done at Tonawanda. Thanks again for all the help!
