Cometic Chevrolet Gen-3 Inline 6 .027in MLS Cylinder Head Gasket - 4.125in Bore

If you're working on a Chevrolet Gen-3 Inline 6 engine, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the job. It's designed with a 4.125-inch bore and a compressed thickness of .027 inches, making it suitable for a wide range of classic Chevrolet and Buick vehicles from the 1960s and 70s, like the Chevrolet C10 Pickup or Buick Skylark. These gaskets are a solid choice for rebuilding or repairing your engine's top end.

Cometic constructs these MLS gaskets from multiple layers of stainless steel, which gives them 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 without needing additional sealants. This construction is ideal for pairing aluminum heads with either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals.
