I searched on these threads but i might have missed something. My question is what headgasket to use. I whant to use the Titan one but i need a different size. I dont know which one though the 86mm or 84mm. From searching i know stock bore diameter is 83 mm i am over boring .040 or 1mm. I think i have to use the 84mm gasket but i can't find it. Do i have to get it custom made or does anyone know where i can find one? Any help is appreciated.
