Unless you have forced induction they will cause massive problems for you because they will allow unmetered air into your motor. As a result, your motor will run like crap.

I disagree, I have 1.7 rocker arms and I had to get Tall Valve covers and drill in my own oil fill because the I take elbow adapter was hitting the oil fill on the ford racing, Edelbrock , and tFS covers I tried so I went with the Moroso tall covers and pre drilled the oil fill in the rear above the # 4 cylinder and use a baffled grommet and breather cap, been on for a year and car runs perfect !!!

I also have the same type of breather with no problems. Not sure if there's any gains, I just didn't think there should be ventilation from the valve cover to the intake.
