Cometic copper head gaskets are manufactured using high-quality materials and precision manufacturing processes. The copper construction allows the gasket to conform to minor surface imperfections while maintaining an excellent seal under extreme cylinder pressures and temperatures. These gaskets require smooth surface finishes (recommended 50 RA or better) and proper sealant application for optimal performance.

Compatible with Chrysler B-series (350, 361, 383, 400) and RB-series (383, 413, 426, 440) big block V8 engines. Sold individually - two gaskets required per engine.
