Hey Guys,
I'm trying to get my car finished up and I really need a new set of headers. I'm just wondering if there is any E.T. in going with SS?

I cannot see where there would be any ET in a material change from mild steel to stainless.
The ET in headers is purely design, tube diameter, and tube length. Coating is worth as much as 2.5%. The correct steps in tubing diameter can be worth as much as 2%. In order to take full advantage of merge collectors, a cam change may be necessary. In order to make a set of "tri-Y" or 4-2-1 headers work, as opposed to s set of 4 into 1 headers, you would probably also need a cam change. Jere Stahl has closed his doors, the only thing he's shipping now is pre bent kits he had left over. If you want 4 into 1, Kromer is building headers again, or Mark Lelchook. For 4-2-1 stuff, you have Calvin Elston and Mark Lelchook. I have friends running headers from all three of those shops, and all are happy.

For a Ford you might give REF headers in Arizona a call 928-692-0111. I have had them on a Mustang and Torino and have been happy with the product and the service. They have the jigs and if you need a change they can do it over the phone. Like going from a auto to a stick.

There is performance is stainless, just as coating
Helps ,stainless keeps heat in way better than Mild steel. The heat retention of a stainless header Is every bit as good or better than coated mild Steel and they won't rust

Save your money and just use the mild steel. Have them coated by a good company and they will last a long time. REF in AZ has all the jigs for your car also.

No, the heat retention of stainless steel is no where near that of mild steel with a ceramic thermal barrier coating.

The coefficient of thermal conductivity for mild
Steel is 26.98 stainless ls 9.3 and mild steel Conducts 219 % more heat pr ft than stainless. I have shot my header tubes with a infrared Heat gun both coated and stainless and not Once have I seen mild better. Ever see a pro Stocker with coated headers, if they were better I'm sure they would be using them!
