Intake Gasket Set - BBC 1.75 x 2.500

The Intake Gasket Set – BBC 1.75 x 2.500 from Cometic Gaskets is engineered for serious big-block Chevy builders and enthusiasts who demand reliability in high-performance applications. This precision gasket set seals the critical interface between your intake manifold and cylinder head, preventing coolant and fuel mixture leakage that can compromise engine efficiency, cooling system integrity, and long-term durability. Whether you're assembling a street engine, competition build, or restoration project, a quality intake gasket set is non-negotiable for baseline engine performance and longevity.

Cometic's gasket technology employs advanced elastomer and composite materials designed to withstand the thermal cycling and pressure fluctuations inherent to BBC engines running at elevated boost or naturally aspirated power levels. The 1.75 x 2.500 dimension specification ensures proper sealing geometry for compatible BBC manifold and head configurations, while the gasket's compression characteristics maintain a consistent seal across repeated heat cycles without creep or deformation. This intake gasket set is manufactured to OEM-equivalent or superior tolerances, delivering reliable clamping load retention and preventing the gradual seal failure that can lead to coolant weeping, air leaks, and performance loss over time.

Mechanics and engine builders working on big-block Chevrolet platforms—including 427, 454, 496, and other large-displacement variants—rely on Cometic intake gasket sets to eliminate guesswork during assembly and rebuilds. Proper installation requires correct manifold torque sequencing and specification-grade fasteners; following OEM guidelines ensures the gasket develops full sealing capability immediately upon engine startup. This gasket set is an essential component for any BBC rebuild targeting reliability, whether the engine sees street duty, weekend racing, or marine service. The compact 5.1 x 23.05 inch package dimensions make it easy to stock alongside other critical gasket components for complete engine assembly.
