The only thing I would add is that in 1931 my Duesenberg headers were porcillinized bottle green. I recentely had them redone by Praire Porcillin. They did a great job.

One of the chat members had his headers cc'd on both inside & outside. Wouldn't the inside coating insulate the metal from a lot of the heat?

I think you mean ceramic coated. Anyway, CC'd headers , on average, run hotter inside than their stainless steel equivelants, for this reason the exh. gases flow w/ a greater velocity, and are allegded to perform better. The down side is: since the op. temps. are higher, the header/components will fail, or succumb, to heat stress sooner than a component not made with such an insulating material; it's the same thing that happens to heatwrapped headers/exh. components. |

I've been hearing lately about porcelaining exhaust headers.
What is the reason for this?
Is it better for heat?
Do you not need all the heat shrouding?
Where do you get it done?
How much?
