Cometic MLS head gaskets are constructed from multiple layers of stainless steel, with each layer serving a specific purpose to create a superior seal. The outer layers are embossed to provide sealing pressure around combustion chambers, coolant passages, and oil passages, while the inner layers provide structural rigidity and recovery characteristics. This design allows the gasket to maintain seal integrity under extreme thermal cycling and high boost conditions, making it an excellent choice for both stock rebuilds and performance applications.
