318 Valve Covers ?

Looking to get a new set of valve covers. My question is the stock ones I have on have a pcv on one and a vent hooked up to the bottom of the air cleaner on the other. The Mopar Performance ones only has oil caps on both. Can I dis regard the pcv and vent to air cleaner or do I need to add this back. I am switching over to a Edlebrock Carb and Intake at the same time as the valve covers.

Thanks,
