Cometic MLS head gaskets are engineered for street performance, racing, and boosted applications where OEM gaskets fall short. The multi-layer design allows the gasket to adapt to head and block movements during thermal cycling while maintaining consistent combustion sealing. These gaskets are ideal for engine builders seeking precise thickness control for compression ratio optimization.
