If you could get something like the Durametric or a Foxwell that reads cam deviation or cam angle. one of those would work.
I have both. on either scanner I can look at Camshaft deviation on each bank.

I can also look at actual cam angle while the car is running so I can compare one bank to the other to see if they are close to each other or are the numbers way different from one bank to the other.
That is what I would want to look at in your case with the sensor testing good.

If your tool is able to test the cam position sensor and it tests good then it is probably ok. I believe the scanner is reading what the DME sees.
