I'd rather not spend 100 bucks on a headgasket with +.020 over bore. Does anyone know where I can get one for cheaper than that? its for a D16Z6 bored to 75.5mm (.020 over) Or Has anyone ever modified a regular bored one to fit? It would only be a quarter of a millimeter around the edge. I figured a dremel would work but I'm worried it would weaken the headgasket. O and my CR will be around 11:1 Thanks guys.
