About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chevy Gen 1 Small Block V8 engines with a 4.030-inch bore. It's built with multiple layers of stainless steel, giving it increased strength and the ability to rebound, which helps it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, meaning you won't need any extra sealants for a good seal. This gasket is a solid option for both aluminum heads on aluminum blocks and aluminum heads on cast iron blocks, as it can handle the shearing forces that can occur between different metals.

The compressed operating thickness of this gasket is 0.036 inches, with an uncompressed thickness of 0.051 inches. This design makes it suitable for high-output engines. The multi-layer steel construction provides a strong seal that can withstand significant pressure, and the Viton coating on the outer layers ensures a reliable seal against the cylinder head and block surfaces. This gasket fits a wide range of vehicles from the early 1980s, including popular models like the Chevrolet C10, Camaro, and GMC C1500.
