Product Details
This Cometic Multi-Layer Steel (MLS) head gasket is what you get when you need a solid seal for your GM L18 Vortec 8100 Gen-VII Big Block V8 engine. It’s built with multiple layers of stainless steel, with the outer layers coated in Viton, a heat-resistant rubber material that can handle up to 482°F. This construction means it’s ready for high-output engines and works well with both aluminum and cast iron blocks, resisting the shearing forces that can happen when different metals meet.
The gasket has a compressed operating thickness of 0.098 inches and a 4.350-inch bore, designed to fit a range of heavy-duty trucks and SUVs like the Chevrolet Silverado 2500 HD and GMC Sierra 3500. Because it's an MLS gasket, it doesn't require any extra sealants, making installation more straightforward. The multiple stainless steel layers not only add strength but also help the gasket rebound and resist corrosion, ensuring a reliable seal over time.
