Here is what Toda has to say about their product:

With increased pressure found in the combustion chamber, blowout occurs with factory head gasket, especially with high compression normally aspirated and high boost turbo engines. To prevent this, Toda Racing designed the stopper type head gasket for some of the popular Japanese vehicles. Whether it's normally aspirated or turbo charged, total sealing between the cylinder head and block is insured.
