So, I have an aluminum Weiand early 2x4 Caddy intake. Over the years the dowel has worn a hole in the intake. I was going to weld up the holes and redrill, but then I started to wonder if I even need them? Were they just because the old intakes weighed 60 lbs? Or do they actually have a function, like holding the gaskets in place? I just need to get this done, so I can get it to the polisher.
