I struggled today with the intake. My welds have leaks in several places based on putting acetone on the welds and seeing where it bleeds through. I've attempted some brazing on the manifold today as well. I brazed up the areas between the runners where it goes through the tube fairly successfully, but when I attempted to braze up the MIG seams to seal them up, I didn't like the warping the metal was doing during the heating so I did not pursue it further and will cover the welds with epoxy before painting. I also attempted to use the brazing rod to fill in the openings on the port entry and over all failed miserably. So I MIG'd a bunch of metal all over the place and took a grinder too it. It's about as good as it'll get and soon be hidden, but reasonably functional.
Set the other end of the tube on it for a visual of what it'll look like in there.
