Pulley Issue?

I have put AC pulleys on my 73 455. I'm seeing a mismatch in the belt riding in the pulley grooves. I'm thinking this is causing an issue as they would be trying to go different speeds causing belt wear and noise. What do you think? Do I have incorrect belt width, or is my thinking off? Wider belt for PS pump?
