It is made for rebuilt and modified engines where the head seal has to hold more cylinder pressure than a factory gasket.\u003c\/p\u003e\n\u003cp\u003eIt has a 101.5 mm bore and is 0.8 mm thick at the combustion seal (Siruda's figure; body thickness is in the specifications).\u003c\/p\u003e\n\u003cp\u003eSiruda's stopper design adds a stopper layer sandwiched between the steel layers around each bore. It keeps the combustion seal stable under engine vibration, and the compact seal suits engines with little room around the combustion chamber.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Sold individually: this engine needs two, one for each cylinder head.
