What's the best engine paint for the red that's on the early slant 6s and 273s?

You really can't compare the fresh paint to a 50 year old aged, overheated, crusty, throttle spring bracket. That's why I used my distributor. It was pretty protected and the new paint out of the can was a real close match.
I certainly can, especially, when I compared this area to the back of the distributor when I pulled the motor, and they looked exactly the same.
