Review GM Big Block Cylinder Head Nos fits 366 427 1966-84

The 1966-1984 GM 3917218 366/427 Big Block Cylinder Head is a classic piece of automotive history. This cylinder head is designed for use with the iconic 366 and 427 cubic inch engines, which were renowned for their power and reliability.

The 3917218 cylinder head is a cast-iron unit, featuring a quad-port intake design that allows for optimal airflow into the engine. The ports are sized and shaped to provide a smooth and efficient airflow path, which is crucial for maximizing engine performance. The intake ports are also canted, which helps to reduce turbulence and improve combustion efficiency.

The cylinder head also features fully-adjustable valves, which allow for easy tuning and adjustment to optimize engine performance for different driving conditions and fuel types. The valves are operated by dual-spring valve springs, which provide a consistent and reliable valve action.

The cylinder head also features high-quality valve guides and seats, which are designed to provide a tight seal and minimize leakage. The guides and seats are made from a durable material that can withstand the high temperatures and pressures generated by the engine.

The cylinder head also features a high-quality, multi-layer cylinder head gasket, which is designed to provide a reliable seal between the cylinder head and engine block. The gasket is made from a high-temperature, high-pressure material that can withstand the extreme conditions encountered in the engine.

The 1966-1984 GM 3917218 366/427 Big Block Cylinder Head is a high-quality, durable, and reliable component that is ideal for use in performance applications. Whether you're building a hot rod, restoring a classic car, or simply looking to upgrade your engine, this cylinder head is a great choice.
