[benckie]

what to look out for when using copper gaskits wih your engines, for maxium power and revs keep an eye out for this, it can easly be fixed with a dremel or a small file













the only copper gaskits ive found sofar that don't need a grind or file to fit corectly are the zen 4 bolts bolt stright up no mods needed
