Gas or Tig. As Tig should be stronger.
Their site says Gas. Nothing is wire fed.
To our valued customer, “We make the highest quality headers available.” Before you install these headers, please check out our quality. Look inside the collectors, there is no “Wire” or "Bee bees" from the welding sticking to everything. They are gas welded inside because this is better. Gas welding is better on the insides because it will last about twice as long as “Wire feed“ welding. This is because gas welding flexes more. Think about how the engine twists on acceleration, and shakes while idling. All of this motion is transmitted through the exhaust system.
The header flanges are ground flat and deburred so they are smooth inside. Our headers utilize the entire machined surface of the head for a gasket surface (not an “o” ring gasket area like other headers). A flat header surface will not warp like "o" ring ports do.
These headers are clearanced for the header bolts and box end wrenches. Can you imagine that? Someone in the automotive business is concerned about accessing parts and fasteners. We think that's unique.
We make the best headers because all of our header builders take pride in what they make. These builders are the reason you are looking at this quality. Without them we would be only machines and equipment. Our entire staff work as a “team” and will always give our customers 100 percent. As a business owner I consider myself “Blessed” to have this quality in my employees.
Please accept my sincere thanks for choosing “Stan’s Headers”.
Respectfully yours:
Stan Fuller
