Int Gasket - 18 Deg.Chev 1/16

The Int Gasket - 18 Deg. Chev 1/16 from Mr. Gasket is a precision intake manifold gasket engineered for small-block Chevrolet engines requiring an 18-degree angled sealing surface. This gasket sits at the critical junction between your intake manifold and cylinder head, sealing combustion pressure and preventing vacuum leaks that can degrade engine performance and fuel economy. Whether you're rebuilding a classic muscle car, upgrading a street rod, or restoring a high-performance Chevy engine, a quality intake gasket is non-negotiable for reliable operation and peak efficiency.

Manufactured to OEM-equivalent standards, this 1/16-inch thickness gasket is designed to compress and conform under the clamping load of manifold bolts, creating a dependable seal across the entire seating surface. The 18-degree angle matches the specific head geometry of compatible small-block Chevrolet platforms, ensuring proper fitment without modification and eliminating the risk of leakage at the mating surfaces. Mr. Gasket's proven gasket material resists fuel, oil, and coolant degradation while maintaining its sealing integrity across normal engine temperature cycling—critical for longevity in both street and light competition applications.

This gasket is ideal for mechanics and enthusiasts performing intake manifold removal, cylinder head work, or complete engine rebuilds on small-block Chevy engines with 18-degree head angles. Installation is straightforward: ensure both the manifold and head surfaces are clean and dry, position the gasket on the head studs, then torque the manifold bolts to factory specifications in a cross pattern for even clamping pressure. Proper installation eliminates vacuum leaks, prevents coolant seepage, and protects your investment in engine modifications or restoration work.
