Cometic GM LS1 SB 4.160 inch Bore .075 inch MLS-5 Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with a 4.160-inch bore and a compressed thickness of 0.075 inches, making it a solid choice for GM LS Gen-3/4 small block V8 engines. It’s designed to handle the demands of high-output applications, whether you're working with aluminum heads on aluminum blocks or aluminum heads on cast iron blocks. The MLS construction offers increased strength and resistance to corrosion, thanks to its multiple stainless steel layers.

The outer layers of this gasket are embossed and coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. This coating ensures a reliable seal even in harsh conditions and across various surface finishes. The center layer is uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine build requirements. Because it's a multi-layer steel design, it doesn't require any additional sealants for installation, simplifying the process.

This gasket fits a wide range of GM vehicles, including models like the Chevrolet Silverado, Corvette, and Cadillac CTS. It's a well-built component designed for maximum sealing performance in demanding engine builds.
