4.080 MLS Head Gasket .030 - SBC Vortec

The 4.080 MLS Head Gasket .030 - SBC Vortec from Cometic Gaskets is a precision-engineered engine seal designed for small-block Chevrolet and Vortec applications. This gasket is ideal for mechanics, engine builders, and performance enthusiasts who require reliability during high-stress engine assembly.

Manufactured using advanced multi-layer steel (MLS) construction, the gasket features a 4.080 bore diameter and .030-inch thickness, allowing for precise compression and uniform clamping load distribution across the cylinder head. The MLS design employs layered steel plates bonded with elastomer, providing superior conformability to machined deck surfaces and reducing the risk of gasket failure under sustained pressure and thermal cycling.

This gasket is essential for anyone performing a small-block Chevrolet or Vortec engine rebuild, whether for truck or performance applications. Its design resists deformation and maintains a reliable seal even in high-RPM or turbocharged environments, making it a critical component for engine longevity and performance consistency.
