Speedmaster MLS embossed head gaskets are manufactured with a high-pressure steel laminate for handling the extreme pressure forces between aluminum cylinder heads and cast-iron engine blocks. The internal embossments expand with high-pressures and temperatures for outstanding sealing attributes. These gaskets combined with high-quality aircraft-grade Chromoly steel head fasteners are great for handling high-horsepower from nitrous, turbos, and superchargers.
