The size of the ports and the severity of the cant will of course vary from barrel to barrel, so I'm not sure if there's a universal acceptable level of cant, but I could be wrong.
As others have said, the bigger issue is what the cant is doing to the gas tube/gas key interface. I would check to ensure they're mating up properly, and if so, I imagine it should be good to go.
