Progress! First set of headers I've ever attempted to build, but so far I'm satisfied with the progress. Before I stitch the tubes together I'm going to get a smaller wire for my welder to reduce the chance of blowing through the metal. Once I have the tubes welded, I'll build a pair of collectors down to the 1.75" pipe, then do final metall stretching and welding to the flange.
I'm going to be giving it more thought, but I think this routing will let me use the pipes I have as is. I just need another 90º coupler or two. This routing will require just one hole through the core support on the driver's side. Then I'll build a new intake manifold and line up the throttle body with the tubing.
