Cometic Chevrolet Mark-IV Big Block V8 .075in MLS Cylinder Head Gasket - 4.320in Bore

Cometic Gasket is well-known for making reliable sealing solutions, and their Multi-Layer Steel (MLS) head gaskets are a popular choice for performance builds. This particular gasket is designed for Chevrolet Mark-IV Big Block V8 engines and features a compressed thickness of .075 inches with a 4.320-inch bore, making it suitable for a wide range of these powerful V8s, including applications in vehicles like the Chevrolet C10 Pickup, Impala, and Corvette from the mid-60s through the mid-70s.

What makes these MLS gaskets stand out is their construction. They are built with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a solid seal even under demanding conditions. This design means you don't need to use any extra sealants, and they work well with both aluminum and cast iron blocks, handling the different expansion rates between materials.
