Cometic Chevy Gen1 Small Block V8 .089in MLS Cylinder Head Gasket - 4.125in Bore - 18/23 Degree Head

When you're rebuilding the top end of your Chevrolet Gen 1 Small Block V8, getting the cylinder head gaskets seated properly is crucial for a good seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of higher output engines, whether you're pairing aluminum heads with an aluminum block or aluminum heads with cast iron. It's designed to provide a strong seal without needing any extra sealants.

Cometic builds these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is stainless steel, and its thickness can be varied to achieve different compressed gasket thicknesses, like the .089 inches this gasket offers. This particular gasket is made for a 4.125-inch bore and features steam holes and a round bore design, suitable for 18/23 degree cylinder heads.

This gasket fits a wide range of vehicles from the early 80s through the mid-90s, including many Chevrolet C/K series trucks, Camaros, Corvettes, and Monte Carlos, as well as GMC trucks. Make sure to check the fitment details to confirm it's the right part for your specific application.
