The Greddy Metal Head Gasket for the Nissan R35 GT-R (or VR38DETT owner!), is built with the intention of holding down enormous power. Greddy's design includes a "stopper ring" around the cylinder which provides a folded layer of thickness that is able to seal the cylinder and protect under extreme boost. We highly discourage anyone from purchasing metal head gaskets for their VR38DETT that do NOT include this type of technology.
Our proof in this matter is from the multiple head gaskets we were blowing in 2010, when there was no current manufacturer of proper metal head gaskets for the R35.
