Cometic Chevrolet Gen-1 Small Block V8 .030in MLS Cylinder Head Gasket - 4.160in Bore

Starting with a compressed operating thickness of 0.030 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing performance. It’s constructed from multiple layers of stainless steel, which gives it strength and the ability to rebound, helping it resist corrosion and handle the stresses of high-output engines. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, making it suitable for both aluminum and cast iron blocks. This gasket is designed for aftermarket heads and features undersized water ports that allow for customization during installation.

The multi-layer steel design means you don't need to use sealants, and it’s engineered to handle the shearing forces that can occur when mating different metals, like aluminum heads to cast iron blocks. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements, though this specific gasket has a compressed thickness of 0.030 inches. This gasket fits a wide range of Chevrolet Gen-1 Small Block V8 applications, including vehicles like the Chevrolet C10, Camaro, and Corvette, as well as many Buick and GMC models from the early to mid-1980s.
