SB Ford Header Gaskets 260-302

The SB Ford Header Gaskets 260-302 by FEL-PRO are precision-engineered sealing components designed for small block Ford engines with spread-port cylinder heads. These gaskets seal the critical interface between your exhaust headers and cylinder head ports, preventing hot exhaust gases from leaking into the engine bay or past your gasket surfaces. Whether you're restoring a classic muscle car, upgrading an older truck, or building a high-performance street engine, proper header gasket selection is non-negotiable for reliable, emissions-compliant operation.

These gaskets feature a steel core laminate construction with 1.420 x 1.620 inch peanut port dimensions, engineered to match the unique port geometry of spread-port small block Ford heads. The laminate design combines the heat resistance and durability of metal with the conformability needed to seal against surface irregularities common in cast iron heads. This construction resists blowout under sustained exhaust pressure and temperature cycling, maintaining a tight seal through thousands of heat expansion cycles—critical when running headers without a traditional manifold's structural support.

Builders and mechanics upgrading to headers on 260, 289, or 302 cubic inch small block Fords will appreciate that this pair covers both cylinder head ports for a complete installation. FEL-PRO's reputation for quality gasket materials means you won't experience premature failure or exhaust leaks that compromise performance tuning or create underhood heat problems. Installation is straightforward: ensure header and head surfaces are clean, install gaskets dry (no additional sealant required), and torque headers to specification. These gaskets are essential whether you're doing a bolt-on header swap or running a built engine at the strip.
