I have a 200 block from a 78 Fairmont with a 63 head (small log). The car has a valve cover with the PCV hose and I also have another valve cover that I think came with the 62/63 motor without the PCV outlet. I would rather use the one without the PCV because my air filter does not have this attachment port. Will this cause me problems with engine performance or life? This is a 1962 Falcon. Thanks.
