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\u003eChoose the bore and thickness to suit your build. It comes in bore sizes of 87 mm or 88 mm and thicknesses of 1.2 mm, 1.3 mm, 1.4 mm, 1.6 mm, 1.7 mm, 1.9 mm or 2 mm. A thicker gasket lowers compression and adds piston-to-head clearance, so measure deck height and set the thickness with your engine builder. The thickness shown is Siruda's figure at the combustion seal; the body thickness is in the specifications.\u003c\/p\u003e\n\u003cp\u003eSiruda's grommet design puts a metal grommet around each bore to hold back combustion gas under high cylinder pressure, including the spikes that come with knock. The grommets are molybdenum coated to limit scuffing of the head and block faces, and a nitrile rubber coating on the gasket surface helps seal the coolant and oil passages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Sold individually.
