ADHD, TL072 vs TL082

So, the ADHD calls for TL082 and I just realized I accidentally ordered the 72 and don’t have 82 on hand. Any major differences? Issues with going with the 72?
 
Since we're talking op-amp substitutions, I'm wondering if anyone has tried 4558s in circuits that use 4580s?

I have a Disarray board ready to build, but I realized I don't have 4580s. I thought I had some but it turns out they are 4558s.

I don't doubt they will work, just wondering if I'd be missing out on some mojo that only 4580s provide or some such?
