my '78 PCV valve only has the one connection, never saw a PCV valve with two so don't know the answer for you but it would be in your AIM if you have one. If you don't have the AIM for your car you really should.

On my 82, one to the PCV & the other to the charcoal cannister. It is a smaller diameter line.
