Cometic Chevrolet Mark-IV - GM Gen-V/VI Big Block V8 .027in MLS Cylinder Head Gasket - 4.310in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring Viton rubber coating on the outer layers. It's designed with a compressed operating thickness of 0.027 inches and a 4.310-inch bore, making it suitable for high-output engines and aftermarket cylinder heads like Brodix Big Duke/Brodie Heads. The undersized water ports allow for custom fitting to your specific setup.

MLS gaskets are known for their ability to handle the demands of modern engines, providing maximum sealing performance without needing additional sealants. They are well-suited for combinations of aluminum heads with aluminum or cast iron blocks, as they can manage the shearing forces that arise from dissimilar materials. The multiple stainless steel layers offer increased strength and resistance to corrosion, while the Viton coating on the outer layers can withstand temperatures up to 482°F (250°C), ensuring a reliable seal in harsh conditions.

This gasket fits a wide range of Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 applications, including models like the Chevrolet Impala, C10 Pickup, and Corvette from various years. It's a solid option when rebuilding or upgrading your engine's top end.
