4.030 MLS Head Gasket .040 - SBF

The Cometic Gaskets 4.030 MLS Head Gasket .040 (C5511-040) is a precision-engineered multi-layer steel cylinder head gasket designed specifically for Small Block Ford engines. This gasket is essential for high-compression and performance applications where standard OEM gaskets may not provide adequate sealing integrity.

With a .040-inch compression thickness and a 4.030-inch bore diameter, this gasket is optimized for SBF engine blocks, ensuring reliable containment of combustion pressure and effective coolant circulation. The multi-layer steel construction is recognized in the industry for its ability to resist blow-out under elevated boost pressure and thermal cycling, making it a superior choice over single-layer alternatives.

Ideal for engine rebuilds, stroker swaps, and turbocharged conversions, the 4.030 MLS Head Gasket is particularly beneficial for those refreshing classic 289 or 302 engines or undertaking performance modifications. Its design prevents coolant migration and maintains consistent clamping load across repeated heat cycles, making it suitable for applications that involve track time, towing, or sustained high RPM operation.
