There has been a LOT of discussion on this subject over a ROP. You should check it out. There are apparently two kinds of material that can be used to fill the crossover, some people like one kind and others like the other kind (aluminum from old pistons and a zinc material from somebody like Mondello). I don't know as I havene't done it. I know that everyone that has used plugs agree that they will rattle with time. Whatever you do, good luck in the endeavour.
