Cometic Chevy Gen-1 Small Block V8 .140in MLS Cylinder Head Gasket - 4.200in Bore

Starting with the embossed stainless steel layers, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of higher output engines. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F, making it suitable for sealing aluminum heads to cast iron blocks or aluminum to aluminum. This construction helps it withstand the shearing forces that can occur between different metal types.

The center layer is stainless steel and can be varied to achieve different compressed thicknesses, like the .140 inch thickness on this particular gasket, which also features a 4.200 inch bore. This design means the gasket provides maximum sealing performance without needing additional sealants. It's a well-built option for rebuilding or upgrading the top end of a wide range of Chevrolet Gen-1 Small Block V8 engines, including popular models like the Chevrolet C10, Camaro, and GMC C1500.
