Each flange is manufactured from durable steel and finished in a natural surface that is ready for installation, coating, or finishing as needed. The pair configuration provides the components required for a matched installation on both sides of the engine.\u003cbr\u003eThe 5\/16-inch-thick construction helps provide dependable support for header tubes while resisting distortion under typical engine operating conditions. The oval port design is engineered for compatibility with headers using a 1.57 x 2.25-inch port opening, helping promote proper alignment during fabrication or replacement work. The flange profile is well suited for custom header projects, repairs, and performance exhaust system installations on Big Block Ford engines.\u003cbr\u003eDesigned with practical fabrication needs in mind, the Patriot Exhaust H7871 offers a solid foundation for building or restoring a custom header assembly. Its steel construction provides durability for workshop and race-oriented applications, while the clean, natural finish allows installers to select the final treatment best suited to their project.
