      PCV valves are commonly ported at the base of the carburetor. Which PCV? Pick one from just about any engine that hovers around 350 cubic inches. Make sure the direction of flow is correct.

      You don't mention which intake you have or whether it has ports for PCV. Some intake vacuum ports are for power brakes. - Dave

        As Dave mentioned we need to know what intake you have. Most post 1964 Ford 352/390 engines use valve covers that have a PCV port and that feeds either into the carburetor if it has a PCV vacuum port or the carburetor base plate that has a PCV vacuum port. Most aftermarket intakes do not have a PCV port. Some Ford intakes have a PCV port in the back that replaces the road draft tube that your '59 originally came with.

            Here's a picture of how the intake connects to the PCV valve and the carburetor base plate as it came from the factory. You need all these parts to use the stock PCV valve. At the least you need a carburetor base plate that has the PCV vacuum connection. If you don't have the screw in type of connector you can just use rubber hose and any PCV valve that will fit snugly into the hose. If you have the screw in connector you can use this PCV valve. https://www.larrystbird.com/product/a6666a-pcv-valve/

              I have a plate under the carb just need to know what pc valve I need to use. I have seen some pc valves hooked to breather caps on valve cover.

                Post a picture of your engine so we can see what you are dealing with. If you don't have the parts in the diagram you will need to experiment with different PCV valves to see what fits. You are trying to use a non factory configuration on your '59. There is no PCV valve designed for your car.
