Copper Header Gasket Set Rectangle Port Fits Ford Small Block SBF 289 302 351W Solid Copper Exhaust Manifold Gaskets Reusable Design No Sealant Required

This copper header gasket set is designed for Ford Small Block SBF engines using rectangular exhaust ports, including 289, 302, and 351W applications. Built from solid copper, these gaskets are intended to provide reliable sealing under high exhaust temperatures without relying on composite layers or sealant coatings. Copper gaskets are commonly used in performance and restoration builds due to their ability to conform during installation and withstand repeated heat cycles. When installed on clean, flat flanges with proper torque, they can be reused during future service or header changes. This set includes two gaskets to cover both sides of the engine. The port layout matches standard small block Ford rectangular exhaust port spacing. These gaskets are compatible with most aftermarket headers and factory style exhaust manifolds designed for the same port shape. Installation notes: Surface preparation is critical. Header flanges and cylinder head surfaces should be clean and flat. Follow recommended torque specifications and recheck fasteners after initial heat cycles. This gasket set is intended as a direct replacement style solution for small block Ford exhaust sealing needs without exaggerated performance claims or unnecessary additives.

• PRECISE SBF FITMENT: Designed for Ford Small Block engines with rectangular exhaust ports including 289, 302, and 351W cylinder heads. Intended for standard small block Ford exhaust flange layouts.
• SOLID COPPER CONSTRUCTION: Manufactured from solid copper for consistent heat tolerance and long service life. Copper construction allows the gasket to conform to minor flange irregularities during installation.
• REUSABLE GASKET DESIGN: Copper material allows for reuse when removed carefully. No fiber layers or composite coatings to burn out under repeated heat cycles.
• NO SEALANT REQUIRED: Designed to seal without RTV or additional sealants when installed on clean, flat mating surfaces. Proper torque sequence and fastener condition are required for best results.
• COMPLETE PAIR SET: Includes two header or exhaust manifold gaskets to service both cylinder head banks. Suitable for headers or factory style exhaust manifolds with matching port shape.
