Cometic GM Gen-V/VI Big Block V8 .030in MLS Cylinder Head Gasket - 4.320in Bore

Cometic Gasket is well-known for making dependable sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on a GM Gen-V/VI Big Block V8 engine, this gasket is designed to provide a solid seal for your cylinder heads. It's built with a compressed operating thickness of 0.030 inches and a 4.320-inch bore, making it suitable for a range of these powerful V8s, including those found in Chevrolet C1500 and GMC K2500 Suburban models from the early to mid-90s.

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