My concern is that with the differing radius rings, the needed ring tension would be varied from piston to piston after filing.

To me, it is not a quality product.

I had no intention of filing the rings , I contacted the dealer I bought them from and he is sending me a new set directly from the manufacture. I think the box was opened and the contents was messed with.

You are not going to check and modify for correct fit?

Checking and preparing to modify the rings is how I found out the rings were different sizes. I have figured my end gap around .015 two of the rings were already .025 . Already to large to file so after seeing the different sizes I never had any intention on filing these rings.

I think we are discussing two different procedures.
