Header Gasket Set - SBF 302/351W 1-5/8

The Header Gasket Set - SBF 302/351W 1-5/8 from BBK PERFORMANCE is a precision engine seal engineered for Small Block Ford applications, specifically targeting the 302 and 351W engine families. This gasket set exists because header-to-cylinder head interfaces demand absolute sealing integrity; any leak compromises exhaust scavenging, reduces horsepower, and allows combustion gases to escape uncontrolled. Whether you're rebuilding a stock engine or upgrading a performance build, a quality header gasket set is non-negotiable for reliable operation and peak efficiency.

Constructed from carbon composite material, this gasket set features 1.625 x 1.500 inch rectangular port geometry that matches OEM and most aftermarket header designs for SBF platforms. The carbon composition resists thermal cycling and maintains compression under the extreme temperatures generated at the exhaust port interface—typically 1,000–1,400°F in sustained operation. The pair configuration ensures you have matched gaskets for both sides of the engine, eliminating guesswork during installation and guaranteeing symmetrical sealing across all cylinders. BBK's manufacturing standards ensure consistent thickness and material density, critical factors that prevent blow-by and premature gasket failure.

Mechanics and enthusiasts rebuilding 302 or 351W engines—whether in Mustangs, F-series trucks, or performance street rods—benefit from this set during header installation or replacement. Installation is straightforward: position gaskets against cylinder head ports, align header flange, and torque fasteners in a cross pattern to manufacturer specifications. This gasket set works with factory iron manifolds and aftermarket tubular headers alike, making it a versatile choice for both stock restoration and bolt-on performance upgrades. For anyone serious about exhaust sealing without the risk of repeat failures, the Header Gasket Set - SBF 302/351W 1-5/8 delivers proven reliability at a competitive price point.
