What year is your Valor?
The sights, and sight cut, changed from the 2009 to 2010 and later years.
The rear for '08s and '09s is a Novak LoMmount cut. 2010s and later have Heinie cuts.
Novak offers sights for lots of different pistols (with different dovetail cuts), so the appropriate dovetail design will need to be chosen.
