4.080 MLS Head Gasket .051 - SBM

The 4.080 MLS Head Gasket .051 - SBM from Cometic Gaskets is a precision cylinder head gasket engineered specifically for small block Mopar engines. It is designed for builders and enthusiasts who require reliable, leak-free performance under demanding conditions, making it ideal for both street applications and high-performance builds.

Constructed from advanced multi-layer steel (MLS) technology, this gasket provides superior conformability and reusability compared to traditional composite gaskets. The 0.051-inch compression thickness is precisely calculated to maintain the correct combustion chamber volume and quench distance, optimizing flame propagation and detonation resistance for enhanced engine performance.

Small block Mopar engines, including the 318, 340, and 360 variants, benefit significantly from Cometic's precision engineering, especially in rebuilt or performance-enhanced applications. Proper installation requires adherence to head bolt torque sequences and ensuring that mating surfaces are resurfaced for maximum effectiveness. This gasket is sold individually and is an essential component for any cylinder head assembly, rebuild, or refresh project on small block Mopar platforms.
