Cast Iron Exhaust Manifolds

The Hooker BlackHeart LS Swap Exhaust Manifolds (HEH 8502-5HKR) are engineered for GM LS engine swap installations where durability and a quiet, leak-free seal are paramount. Constructed from cast iron, these manifolds are finished with a gray ceramic coating, which helps to reduce under-hood temperatures and enhance resistance to corrosion. This coating also contributes to a cleaner appearance in the engine bay. Designed with a tight tuck and block hugger configuration, these manifolds are intended to provide broader fitment for most popular chassis. The package includes nickel-plated steel mating flanges, MLS (Multi-Layer Steel) mating flange gaskets, and the necessary mating flange hardware, ensuring a complete and secure installation. The outlet size is specified at 2.50 inches. These exhaust manifolds are noted as being compatible with 1970-1981 Chevrolet Camaros, fitting closely to the engine. While described as having universal fitment for most popular chassis, specific applications can vary based on engine bay configuration and other components. Additional fitment information is available for various Buick, Cadillac, and Chevrolet models, indicating a broad range of potential applications within GM platforms.
