Cometic Chevy Small Block Brodix (All 12-23 Deg Head) 4.030in Bore .027 inch MLS Head Gasket

Starting with a compressed operating thickness of just 0.027 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious performance. It’s specifically designed for Brodix heads with 12-23 degree valve angles and a 4.030-inch bore, making it a solid choice for many Chevrolet Gen-1 Small Block V8 engines, including models like the Chevrolet C10 and Camaro from the 1980s.

The strength of this gasket comes from its multiple layers of stainless steel, which help it 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 construction means you don't need any extra sealants, and it’s well-suited for combinations of aluminum heads with either aluminum or cast iron blocks, as it can manage the shearing forces between different metals.

The center layer is uncoated stainless steel and can be varied for different thickness needs, though this specific gasket is set at 0.027 inches. It also features undersized water ports on aftermarket heads, allowing for custom porting to match your specific setup.
