A couple of years ago when I made a pass I was getting oil leaking out of my breathers and getting on my headers. I drilled a hole in the front of my passenger side mopar performance valve cover and ran a hose to a catch can and put a moroso header evac in the header on that side and I never had the problem again. The driver side has a hose ran down and just open to air. I also run Bullet mufflers, I have never raced anything with open headers I do not like all the noise. I think mine is way to loud with the Bullet mufflers on it now.
