Francis, I don't have a dog in this fight, but since I have dealt with Sanderson so many times in the past I took the liberty of calling Nick at Sanderson for you.
As I suspected, there is a little more to this story. Evidently, this is your fourth try with different header companies in an attempt to get headers to fit your application. Nick says that they are not welded backwards, this particular V6 header is weird in the respect that the one side exits toward the front...........it has to be that way for the application it was designed for. You are evidently using it on another car/engine setup. I thought originally that these were T bucket style headers, but he says they are of the block hugger variety.
He has offered you a full refund, sans shipping back, because they feel the product is not defective, just not right for your use. We had to pay shipping both ways on a TCI transmission that failed after 200 miles, and we were not happy with that, so I understand your displeasure. For some reason most companies will offer a refund, but it is up to the buyer to cover freight............this includes Summit, Jegs, Pete and Jakes, etc.
Like I said, I am not involved in this in any way, other than to try to get both sides of the story. We have used them now 3 times, and every set of headers has been a work of art. It seems to me that you are making the right decision building your own, as that will probably be the only way to get a set that fit the application you have.
