You need to be careful about the ring spacings.
Campag manage ring spacing in many cases on the ring itself - the tabs are often the same thickness but where on the gauge of the ring the teeth are milled, sets the spacing.
There's also the question of how physically thick the rings are, less of a problem when you have all 5 bolts visible, but still relevant as the thickness of the ring will also potentially affect the ring spacing.

For reference (not relebant in the OPs case) In the case of hidden bolts, because the big ring is supported on both sides, if the ring is too thick or too thin for the crank design, you get a "kink" behind the crank - can cause chain drop.

It's not unusual to get the "chain rides the teeth of the inner ring" problem where you have a mismatch of chain, FD and ring spacings / set-up issues because the FD and LH shifter don't match to the ring spacing.

It's much more commonly a problem running 9 and 10s on 8s rings which wouldn't apply in this case (compact being a more modern innovation than most 8s chainrings allow for - and there were no Campag 8s rings in compact sizes) but we do see it from time to time with mix'n'match set-ups. Sometimes OK in the stand but once tension is on the chain, it happens on the road. It was a bit of a curse back in 2004-06 with the old "Compact" type FDs, mostly cured when they were replaced with QS in 2007.
