Building your own headers.

I have built several sets for my projects. I have used Headers by Ed in Mpls. I do not know if he is around any more. I always position where I want the collector and build the longest tube first and then go from there. My goal was always to build equal length plus or minus 3/4”. Once built I would have them ceramic coated for longevity. I used a piece of welding rod as a basic guide to rough out bends for length and shape. I would tack the tubes with MIG and I fully welded with TIG once they were all together. Think of it as a 3D jigsaw puzzle
