Cometic Chevrolet 348/409 W-Series Big Block V8 .060in MLS Cylinder Head Gasket - 4.437in Bore

This product is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet 348 and 409 W-Series Big Block V8 engines. It features a 4.437-inch bore and is .060 inches thick, intended for engines that have been machined to this size. This gasket is built to provide a solid seal between the cylinder head and the engine block, which is crucial for maintaining compression and preventing coolant or oil leaks.

The MLS construction offers improved sealing capabilities over traditional composite gaskets, especially in high-performance applications. The outer layers of this gasket are embossed and coated with Viton, a high-temperature resistant material that helps create a tight seal against the cylinder head surface. This updated design helps ensure reliable performance and durability for your engine rebuild.

This gasket fits a range of classic Chevrolet vehicles, including models like the Bel Air, Impala, and C10 Pickup from the late 1950s and early 1960s. Always refer to your vehicle's specific service manual for proper installation procedures and torque specifications.
