Exhaust Header Gasket Set SBF 302/351W

The Cometic Gaskets Exhaust Header Gasket Set SBF 302/351W (part number C15572HT) is a premium Small Block Ford manifold gasket set engineered for reliable sealing on 302 and 351W engines. This is a pair of oval port gaskets featuring a steel core laminate construction designed to withstand the thermal cycling and exhaust gas pressure found in high-performance and stock applications alike.

The 1.751 x 1.231 inch oval port configuration matches the port dimensions of Small Block Ford cylinder heads, ensuring precise alignment and consistent clamping load across the gasket face. Steel core laminate construction provides superior crush strength and high-temperature resistance compared to solid graphite designs, preventing gasket blowout under sustained exhaust pressure. This material composition is particularly valuable in forced-induction builds, headers with tight port matching, and extended high-RPM operation where thermal stress on the gasket interface is elevated.

Small Block Ford engine builders—whether restoring stock 302 blocks, upgrading 351W performance platforms, or assembling stroker combinations—rely on OEM-quality gasket sets to prevent exhaust leaks at manifold-to-head interfaces. This SBF header gasket set addresses that requirement with Cometic's proven laminate technology. The pair format provides both left and right bank gaskets needed for a complete manifold installation. Lightweight at 0.22 lbs and compact in profile, this set integrates seamlessly into stock or aftermarket header systems without fitment complications.
