Intake Gasket Set SBC w/23 Degree Heads

The Intake Gasket Set SBC w/23 Degree Heads by Cometic Gaskets is purpose-built for small-block Chevrolet engines equipped with modern 23-degree cylinder heads. Whether you're rebuilding a street engine, preparing a weekend cruiser, or fine-tuning a performance build, this gasket set seals the critical interface between your intake manifold and cylinder head casting. A proper gasket seal at this junction is essential—any leak here causes vacuum loss, rough idle, poor fuel economy, and potential coolant seepage into the combustion chamber.

Cometic manufactures this intake gasket set using advanced elastomer and composite materials engineered to withstand the thermal cycling and pressure fluctuations inherent in modern SBC applications. The 23-degree head designation refers to the valve angle geometry of contemporary aftermarket and OEM cylinder head designs, which differ from classic 18-degree configurations. Cometic's precise engineering ensures a perfect seal without over-torquing fasteners, protecting both aluminum and cast-iron surfaces. The lightweight design (0.25 lbs) minimizes parasitic weight while the gasket profile is optimized for manifold surface variance, reducing leak paths and improving reliability over thousands of miles.

Mechanics and enthusiasts building SBC engines with Brodix, Dart, Trick Flow, or similar modern 23-degree heads depend on this gasket set to maintain vacuum integrity and prevent costly coolant leaks. Installation is straightforward—gaskets lay flat on clean surfaces, require no special sealant, and torque sequences follow standard SBC intake manifold procedures. This set is ideal for both stock-style and performance manifold applications, from carbureted to EFI conversions, and works seamlessly with aluminum or cast iron intakes. Always verify your specific head casting angle before ordering to ensure perfect compatibility.
