Which PCV valve, FV184 or FV163 for a 440?

[themechanic]

The replacement PCV valve by application is the FV163 below



However, some folks are using the more "stock" appearing GM PCV valve FV184 below

.

So, the question is, which one are you using and why?

Use the GM one if you want it to look more like a stock one....
