I have a 400ex and i just got my cylinder bored to a 416 piston 87mm. My original head gasket has a crack on it and me being a dumb *** installed it anyways and saw it leaking oil so i just stopped it and now I'm going to replace it with a new head gasket. My question is do i need to by a special head gasket to fit that size bore or can i just use a stock head gasket. I see on ebay when they sell the big bore kit it comes with head gaskets but are they any different. Please let me know thanks Mike.
