For what it's worth, when I built my '29 Ford roadster quite a few years ago, I used Speedway headers (I lived an hour north of Speedway so I got a lot of my parts from them). The header pipes eventually rusted where the pipes come together and they finally cracked. So, I replaced them with a pair from Sanderson and had them JetHot coated. Much better product, and the new owner had told me he has not had any problems with them, and he has owned the car for 14 years. Sanderson headers were heavier and I think that is why they have lasted longer. If you want chrome headers, I would pay the extra money and get Sandersons.
