Ok here is pic of the manifold. I just had it fly cutted and wanted to make sure that it was still sealed properly and nothing was getting out. So that is the explaination for the discoloration of the manifold. It was professionally TIG and put together. Plus I accidently got some antifreeze on it when I pulled the top hard line as well tonight so that explains some of the orange coloring. I will sand blast it upon request.
