Cometic Chevy Gen1 Small Block V8 .089in MLS Cylinder Head Gasket - 4.080in Bore - Vortec Heads

Cometic Gasket is well-known for their multi-layer steel (MLS) head gaskets, and this C5474-089 is a prime example. It's built for Chevy Gen-1 Small Block V8 engines, specifically designed for a 4.080-inch bore and Vortec heads. If you're working on a classic Chevy, a GMC truck, or even some custom builds like an Avanti II or Excalibur Phaeton from the 80s, this gasket is engineered to provide a solid seal.

What makes these MLS gaskets stand out is their construction. They're made from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This means they can handle the demands of high-output engines and are suitable for sealing aluminum heads to aluminum blocks or aluminum heads to cast iron blocks without needing any extra sealants. The center layer is also stainless steel, and Cometic uses different thicknesses to achieve the desired compressed operating thickness, which is 0.036 inches for this particular gasket.

This gasket is a well-built option for rebuilding or refreshing your Gen-1 Small Block V8. It's designed to fit right and seal effectively, ensuring your engine runs smoothly.
