440 crankcase ventilation

I have a 440 with a twist on breather on one valve cover. The other cover is a twist on oil cap. I'm tired of oil dripping from breather and running down valve cover onto manifold and in general just making a mess. I have a low rise edelbrock intake with a screwed in plug just below where the car sits. Can I simply screw in a nipple and run a hose to a PVC valve to replace the breather or is there more involved. Will motor run too lean. I have chrome headers so an exhaust system is out of the question.
Thanks!!
