I have been told several different stories about how many/what kind etc breathers I should have on my valve covers. I was looking for some advice or different opinions. Right now I have one breather with a hose from the valve cover to the large vacuum port on the back of the intake manifold (this one has an in-line PCV valve because it wouldn't pass inspection a while back without one ????) and one breather with a hose from the other valve cover to the air cleaner. Do I even need either one of these; any help would be appreciated

The motor is a iron head crate motor, Weiand intake, Holley carb, MSD,
standard bells and whistles.

Thanks.
