SBF Exhaust Gasket Set w/351M Heads

The SBF Exhaust Gasket Set w/351M Heads from Cometic Gaskets delivers the precision seal you need when running a 351M engine platform with modern cylinder head configurations. Whether you're restoring a classic Ford muscle car, upgrading an existing small-block build, or performing a complete engine refresh, this gasket set ensures zero exhaust leakage at the critical head-to-manifold interface. Cometic's engineering targets the exact port geometry of 351M heads, eliminating guesswork and failed DIY attempts with undersized or incompatible gasket materials.

Cometic exhaust gaskets use advanced composite and spring-steel construction designed to withstand the thermal cycling and vibration that standard gaskets cannot handle. The 351M head-specific design accounts for the unique port bolt spacing and gasket seating surfaces unique to this engine family, ensuring consistent clamp load and durability across repeated heat cycles. Unlike bargain gasket sets, Cometic's multi-layer composition resists blowout even under sustained high exhaust temperatures and boost pressure, making it ideal for turbocharged, supercharged, or naturally aspirated high-performance applications.

Enthusiasts building or refreshing 351M-powered engines—from vintage Broncos and Mustangs to custom hot rods—rely on this gasket set to eliminate exhaust manifold leaks that compromise both power delivery and engine longevity. Installation is straightforward during head removal or exhaust manifold service; simply match the gasket ports to your manifold bolt pattern and torque to manufacturer specifications. This OEM-quality gasket set pairs perfectly with stock or aftermarket 351M heads and works with both original cast-iron manifolds and modern tubular headers, making it a must-have for any serious small-block Ford rebuild or upgrade project.
