70 Mustang 302 - T-5 Trans I purchased these headers thinking they were stainless and I wouldn't have to worry about rust issues. The tubes are stainless but the flange is steel. I called JBA and all they could say is they never made a stainless flange. What is the point of making a stainless header with a steel flange? Poor advertising. Also to fit had to make a ding in a tube to have clearance around the steering gear box. Should have bought a cheap set of steel headers then got jet hott coating.
