Cometic Chevy Small Block 4.060 inch Bore .086 inch MLS-5 Head Gasket (18 or 23 Deg. Heads)

Starting with the embossed outer layers coated with Viton, these Cometic Multi-Layer Steel (MLS) head gaskets are built to handle the demands of high-output Chevy Small Block engines. The Viton coating is a heat-resistant rubber material designed to seal effectively in tough conditions and on various surface finishes, making them suitable for both aluminum and cast iron blocks. This gasket has a 4.060 inch bore and a compressed operating thickness of 0.086 inches, specifically designed for engines with 18 or 23-degree cylinder heads.

The multi-layer steel construction provides increased strength and resilience, allowing the gasket to rebound and resist corrosion. This design means you don't need additional sealants, as the gasket itself offers maximum sealing performance. They are well-suited for applications where aluminum heads meet aluminum or cast iron blocks, as they can manage the shearing forces that can occur between different metals.

This gasket fits a wide range of Chevrolet and GMC vehicles from the early 1980s, including models like the Chevrolet C10, Camaro, and GMC C1500. It's a solid option when you're rebuilding the top end of your engine and need reliable sealing.
