Product Details
If you're working on a Chevrolet Gen-I Small Block V8 engine, this Cometic MLS cylinder head gasket is a solid choice for your rebuild. It's specifically made to fit engines with 4.155-inch bores and is .040 inches thick, designed for 18/23 degree cylinder heads. This gasket is built without steam holes, which is common for many Gen-I small block applications.
Cometic uses Multi-Layer Steel (MLS) construction for durability and a strong seal. The outer layers are embossed and coated with Viton, a material known for its resistance to heat and oil, helping to ensure a tight seal around the combustion chamber. This advanced sealing technology is designed to increase clamp load, which is especially helpful for open deck block designs, providing a more reliable seal under pressure.
This gasket fits a wide range of vehicles from the early 1980s, including popular models like the Chevrolet Camaro, Buick Regal, and GMC C1500. When you're putting your engine back together, a well-made head gasket is crucial for proper compression and preventing coolant and oil leaks.
