Product Details
If you're rebuilding the top end of your Chevy Gen-1 Small Block V8, getting the right head gasket is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and block without needing extra sealants.
Cometic uses 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 varying surface finishes, making it suitable for both aluminum and cast iron blocks. The center layer is stainless steel and can be varied to achieve different compressed thicknesses, with this particular gasket set to 0.066 inches and a 4.200-inch bore. It also includes features like valve-pocketed bores and steam holes for proper engine function.
This gasket fits a wide range of vehicles from the early 1980s, including models like the Chevrolet Camaro, GMC C1500, and Buick Regal. It's a well-built option for anyone looking to ensure a leak-free seal during their engine build.
