I think most people would run the same duration and lift on both inlet and exhaust, unless they had looked into it alot and had a reason.
It would be ok to run mismatched cams, or cams of different brands.
Of more importance, is that the person installing them knows a fair bit about it and can use a dial indicator and degree wheel or whatever needed to get it dialed. You need adjustabe cam gears.
If the cams are mismatched, the longer duration cam would be on the inlet for N/A.
Adjustable camgears are adjustable, so they can run with any cams. IF you know how to set it up.
