Can anyone ID these aftermarket pistons?

I'm in the process of disassembling a spare 3.0 engine and was surprised to find it has 90.5mm CNC machined aftermarket pistons. The only identifying mark I can find is "58150B". They look to have relatively high deck height, I would love to find out the manufacturer and compression ratio.

Any help is appreciated!
