MLS Exhaust Gaskets .030 SBC w/SB2 Heads

The MLS Exhaust Gaskets .030 SBC w/SB2 Heads by Cometic Gaskets are engineered for small-block Chevrolet engines paired with SB2 cylinder heads. If you're building or rebuilding a high-performance SBC platform, a quality exhaust gasket is non-negotiable—it seals the interface between your cylinder head and exhaust manifold, preventing exhaust leaks that rob horsepower and create noise. Cometic has earned respect in the performance community for precision-engineered gaskets that withstand heat cycling, pressure spikes, and the rigors of street and race applications.

The .030-inch thickness specification is critical for your SB2 head application—it accounts for the specific deck height and combustion chamber geometry of that head family. Cometic's Multi-Layer Steel (MLS) construction combines multiple steel layers with elastomer facing to create a gasket that maintains a reliable seal across temperature swings and vibration cycles without permanent compression set. Unlike older composite gaskets, MLS technology resists blow-by, manages thermal expansion efficiently, and tolerates the abuse of turbo or supercharged applications without sacrificing longevity on naturally aspirated builds.

Mechanics and engine builders rely on Cometic exhaust gaskets when precision matters—whether you're freshening a street engine, assembling a weekend racer, or finalizing a complete SBC restomod. Installation is straightforward during head or manifold removal, and the gasket's durability means you won't be chasing exhaust leaks months after startup. Verify your SB2 head application and deck specifications before purchase to ensure the .030-inch thickness matches your engine's requirements, and always torque manifold bolts in sequence per manufacturer spec for optimal sealing.
