Campy 8 speed question

I have Campy Record 8 speed with ergshifters. I want to change wheels. Local bike shop's Campy "expert" swore up and down to me yesterday that I can use any Shimano compatible 8 speed rear wheel with a 8 speed Shimano cassette. I'm looking to install a Zipp 404 wheelset. Other bike mechanics tell me that no mater how you slice it, Campy will not work properly with Shimano. If I'll going to upgrade my wheel, I don't want to end up with poor shifting or other issues.
Anyone have expertise with this?

Campy 8 spacing is 5.0mm, compared to Shimano's 4.8mm Obviously it will not work properly. Some people may believe that it works adequately but, it certainly can't work perfectly.

A J-tek shiftmate model #1 would correct the problem.

FWIW, Campy 8 spacing and Shimano 7 have the same 5mm spacing.

Local bike shop guy is wrong. Stick with a Campy freehub and cassette.

As others have pointed out there is a difference in spacing. The flip side is that 8s Campy cassettes are scarce these days, so before investing hard-earned dough in a new Campy 8s wheel, take some time to consider your options.

1- buy Shimano 8s wheel, and use a Wheels of Boulder 8s cassette with Shimano spline, and Campy spacing.

2- if you can find a loose cog 8s cassette for the Shimano hub, such as a Sram, buy that and use 7s spacers, or use your existing campy 8s spacer set, or use .008" plastic shim stock, or kraft paper soaked in oil to micro-space the cassette to where it needs to be. (a bit of a skill job, but not really hard)

3- Buy a Campy 9s/10s rear wheel, with a 9s cassette and the Campy 9s/8s spacer conversion kit, so at least you have something you can grow with later on.

The one thing I wouldn't buy is a Campy 8s cassette body rear wheel, as it'll soon be orphaned.
