Intake Gasket - SBC w/MRE 13-Degree Heads

The Intake Gasket for Small Block Chevy with MRE 13-Degree Heads by Cometic Gaskets is an essential component for any SBC engine builder or performance enthusiast running modern cylinder head technology. When upgrading to aftermarket MRE heads with aggressive 13-degree valve angles, the factory intake manifold gasket often fails to seal reliably due to the altered deck geometry and increased combustion pressures. This Cometic replacement ensures a tight, leak-free seal between the intake manifold and cylinder heads, preventing vacuum leaks, coolant seepage, and loss of combustion efficiency that can rob horsepower and cause overheating issues.

Cometic gaskets are engineered using proprietary materials and precision manufacturing to handle the demands of high-compression and turbocharged small block applications. This intake gasket features a composite construction designed to resist fuel, oil, and coolant while maintaining a consistent seal across thermal cycling and pressure spikes common in modified engines. The gasket's composition allows it to conform to the mating surface irregularities typical of aftermarket heads and manifolds, eliminating the pinch-points and micro-leaks that plague standard OEM gaskets. At just 0.39 lbs and measuring 5.1 x 0.25 x 21.6 inches, it integrates seamlessly into your engine bay without adding weight or complexity.

This gasket is essential for any Small Block Chevy stroker, high-rpm street engine, or road race platform utilizing MRE 13-degree heads. Mechanics and engine builders routinely specify Cometic gaskets when assembling performance builds because they eliminate variables during dyno tuning and street validation—no mysterious lean conditions or coolant loss caused by inadequate sealing. Installation is straightforward during intake manifold mounting; ensure all mating surfaces are clean and dry, apply a light bead of gasket sealant if recommended by your manifold manufacturer, and torque fasteners to specification in a star pattern for even clamping load.
