sb valve covers

You can put a twist in breather on each side (don't forget to use the baffles) and get rid of the pcv valve....and obviously plug the carb vacuum port so you don't have a vacuum leak. Autozone has the breathers for about 5 bucks each....that's what I run on my car.

Yeah sure, if you don't mind oil leaks!
You need to have a way to draw the crankcase gases out of the engine. If you don't you'll be posting on here about chronic oil leaks like all the other guys running just breathers do.
