RB aluminum intake manifold

Before i buy a new one, does anyone have a 440 aluminum intake that they would part with? Rpm air gap, performer, weiand, torker..... not looking for big single plane

I got this , w/ a flow sheet ----------

I ran it for a while , then tried a victor that we reworked a little , the victor matches my head flow a little better , but I couldn`t tell any seat of the pants diff. on the street .
