Cometic GM LS9/LSA Gen-4 Small Block V8 .052in MLX Cylinder Head Gasket - 4.100in Bore - LHS

Built with multiple embossed layers of stainless steel, this Cometic Multi-Layer Steel (MLS) head gasket is designed to handle the high output of GM LS9/LSA Gen-4 Small Block V8 engines. The outer layers are coated with Viton, a heat-resistant elastomer that can withstand temperatures up to 482°F (250°C), ensuring a solid seal even in demanding conditions. This gasket features a 4.100-inch bore and a compressed thickness of .052 inches, making it a precise fit for your engine.

MLS gaskets are ideal for sealing aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as they can manage the shearing forces that arise from the different expansion rates of these materials. The multiple stainless steel layers provide increased strength and resistance to corrosion, while also allowing the gasket to rebound. Because they are designed for maximum sealing performance, these Cometic gaskets require no additional sealants, simplifying installation.
