Edelbrock intake gaskets #7203 are specified for 1965–1990 and later Mark IV oval-port Big-Block Chevy engines (396–402–427–454 ci) and are engineered to support optimal flow and sealing. Using MP-2N Micropore composite technology, the gaskets conform to surface imperfections with lower flange pressures and include nitrile port beads to enhance sealing. Choose these gaskets to match Edelbrock oval-port manifolds and cylinder heads.
