you need to install an inline pcv valve. go to holley website and pull up the instructions for the valve covers. it will give you two choices of brands for the inline pcv valve. I think it was beck arnley and fram iirc. If you don't, you will pull a lot of oil into the intake or your catch can.

COPIED FROM HOLLEY Valve cover manual:
NOTE: Some applications, as pictured below, have internal PCV restrictions inside the cover assembly. If your application utilizes this type of connection, an external PCV valve must be added in-line on the hose. If needed, suggested PCV valves are: (1) Beck/Arnley P/N 0450299 or (2) Fram P/N FV340.
