Header Gasket Set - SBC Round-Port 1.875

The Header Gasket Set - SBC Round-Port 1.875 is an essential OEM-quality component for any serious small-block Chevrolet engine build or refresh. Whether you're rebuilding a street engine, prepping a weekend cruiser, or restoring a classic, this gasket set seals the critical interface between your cylinder heads and intake manifold where high-pressure combustion forces demand absolute reliability. MAHLE ORIGINAL/CLEVITE engineering ensures you get factory-specification gaskets without compromise, eliminating the risk of coolant or fuel leaks that plague budget alternatives.

Designed specifically for round-port intake manifolds with 1.875-inch port openings, this set uses premium composite and elastomer materials that withstand thermal cycling, pressure spikes, and the corrosive effects of modern coolant chemistry. The 1.875 round-port specification is the industry standard for SBC applications, making this gasket set compatible with the vast majority of factory and high-performance intake manifolds on the market. Unlike universal gaskets that require trimming or improvisation, MAHLE's precision-engineered set arrives cut-to-spec and ready for installation, saving time and reducing the risk of leaks caused by improper sealing surface contact.

Mechanics and enthusiasts rely on this Header Gasket Set during complete engine overhauls, cylinder head swaps, or manifold replacement work on small-block Chevrolet engines—including 283, 307, 327, 350, and 400 cubic-inch variants. Installation is straightforward: simply clean the sealing surfaces to bare metal, position the gasket set, and torque your intake manifold bolts to factory specification in a star pattern. Keep a set on hand for any SBC project; the lightweight 0.71 lb package fits easily in any toolbox, and MAHLE's reputation for quality means you can finish your rebuild and drive with confidence.
