Anyone have luck re-using the metal gasket between the head and top of cylinder? Not trying to be cheap, just can't seem to find a gasket that says it's for the 2-bolt valve cover style head. My GY6 has the 2-bolt valve cover and the cylinder stud bolt pattern is slightly different than the 4-bolt head pattern. Found this out the hard way when I went to replace existing head with a spare head the previous owner had purchased (old head had stripped plug threads and all carboned up). The gasket with new head doesn't fit my cylinder. If I can't re-use it, does anyone know where to purchase the head gasket for the 2-bolt valve cover head or how to make one?
