Adam,

You probably already know this but the golden color of Mk II headers, especially the Holman-Moody cars, was not necessarily because they were made from Inconel. Inconel, that I have seen, is a much lighter hue of gold with much higher reflectivity.

I am by no means a metalurgic expert, but Lee Holman told me that the patina was the result of wiping down the headers with WD-40 and having it baked onto the header pipes repeatedly. As far as I know, it could be even both: Inconel rubbed down with WD-40.

Regards,
Lynn
