The MAHLE ORIGINAL/CLEVITE Intake Gasket Set for Small Block Chevy Rectangular Port (MS20018, SKU M77MS20018) is a precision-engineered composite gasket assembly designed for small block Chevrolet intake manifold applications. This kit features a 0.12-inch thickness with 1.250 x 2.200-inch rectangular port dimensions, delivering the exact specifications required for proper cylinder head-to-intake manifold sealing on SBC platforms. MAHLE ORIGINAL is a tier-one OEM gasket supplier recognized across the automotive aftermarket for dimensional accuracy and material consistency—critical factors that determine whether an intake manifold seal holds pressure or fails under load.
Intake gasket integrity directly impacts combustion efficiency and prevents coolant or oil weeping into the intake tract. The composite construction of this gasket set provides thermal stability across normal engine operating temperatures while maintaining a reliable seal under cylinder pressure variations. The 1.250 x 2.200-inch rectangular port configuration matches Chevrolet's standard SBC intake manifold casting geometry, ensuring correct fitment without modification. Proper gasket thickness (0.12 inches) accounts for manufacturing tolerances in both the cylinder head and manifold surfaces, reducing the risk of inadequate clamping load or over-compression that can compromise gasket longevity.
Engine builders, restoration shops, and enthusiasts performing small block Chevrolet assembly or intake manifold replacement work rely on this gasket set to achieve OEM-quality results. Whether rebuilding a carbureted or fuel-injected SBC, troubleshooting intake leaks, or freshening an engine long in service, this MAHLE ORIGINAL kit provides the precision sealing surface required for lasting reliability. The MS20018 part number is the specification called for in factory service manuals and is the standard replacement across the Chevrolet aftermarket for applications using rectangular-port intake manifolds on small block platforms.
