OEM "o-ring" gaskets work better than the aftermarket gaskets. I personally went through the whole process of trying to find a good way to stop the leak and ended up cutting both header/y-pipe flanges and having 2 pieces of pipe welded in place. the only down fall about that... your header and y-pipe will become one piece.
