That piece would probably have made my installation a lot cleaner looking. And would have solved my throttle problems. I'll have to look into one of those. Thanks!
I had no flange thickness issues, but did have clearance issues between the two. I ended up grinding away a portion of the header flange (the portion that separates the two inner tubes from the single outer) to allow the intake and exhaust manifolds to center each port. A few tries at the grinding wheel fixed this.
