The 85 uses 24# injectors. I would call them back and ask them to explain why they feel 22# are the right ones.

An adjustable regulator doesn't hurt. The 85 runs at a lower pressure than later models. That's because it 24# injectors rather than 22. So adding some pressure will help atomize the fuel a little better. TPiS did some testing that supports the argument that the 85 responds better with higher pressure.

Is this what they sent you?

I would think you'd have to turn the pressure up. You can install them and check blm counts with a scanner, and see if they run lean or not.
I don't like the Multec's myself, but it's up to you.
