Question about air movement through the TB and EGR

I have been trying to figure out a vacuum problem ever since I got my car back together and today I just thought of something.

I got a 65mm TB from a guy that needed some work done to it to make it work on my Mustang (it's a 97 Explorer TB so the linkage and TPS mounting location was different). It was also missing the throttle plate (butterfly) so I had to make that as well. I used my stock EGR spacer but I machined it out to match the 65mm TB. I was just thinking about buying a new TB and EGR spacer today and it hit me like a ton of bricks when I remembered machining the EGR spacer. It originally had a taper in it but I machined it straight through so the hole no longer has a taper to it. Did I create my vacuum problem by doing this? Was that taper to help create vacuum?
