Product Details
If you're working on a Chevrolet Big Block Gen IV engine, like the 396, 402, 427, or 454, this Cometic Multi-Layer Steel (MLS) head gasket is built to seal it up right. It's designed for a 4.320-inch bore and has a compressed thickness of 0.036 inches, making it a solid choice for many performance applications.
What makes these MLS gaskets stand out is their construction. They're made from multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing jobs and works well with both aluminum and cast iron blocks. This design means you don't need any extra sealants, and the gasket can handle the stresses of high-output engines.
This gasket fits a wide range of Chevrolet vehicles from the mid-60s through the early 80s, including models like the Impala, Chevelle, and C10 pickups. It's a well-built component that’s ready to go to work.
