Thanks

 

The only thing that shows up when I click the link is the word "Details" and "Quantity: 1".

There is no PCV valve in the LT1 covers. There is a vent line that flows air from the throttle body to the passenger side valve cover, connected by a plastic elbow into a rubber grommet in the valve cover. You can substitute a "breather" in that location, but there's no real benefit in doing so.
