Cometic GM LS1 SB 4.130 inch Bore .040 inch MLS Head Gasket

When you're rebuilding the top end of your GM LS Gen-3 or Gen-4 small block V8, getting the cylinder head gasket seal right is crucial for performance and reliability. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of high-output engines, offering a robust sealing solution that doesn't require additional sealants.

Cometic constructs these gaskets 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 tough sealing environments and various surface finishes, making them suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations. This particular gasket features a 4.130-inch bore and a compressed operating thickness of 0.040 inches, designed to meet specific engine build requirements.

This gasket fits a wide range of GM LS engines found in vehicles like the Chevrolet Corvette, Cadillac CTS, and Chevrolet Silverado. It's a well-built component designed for a direct fit, ensuring you can get your engine back together with confidence.
