std setup would be a PCV in one valve cover (plumbed to carb base) & a breather in the other valve cover. Not sure which one would be the best (flow amt) for your app & that is new area for me & I'm sure would depend on the cam etc but there is a pic/info of an adjustable one ($$$$$) on page 3 in Q&A. I would Google it also

Google ME Wagner and order an adjustable PCV valve from them. Anything else is a waste of time.

A stock pre 1970 PCV bolt in held with a nut with the stock push on PVC style cap will work fine for your application with the existing K&N breather cap. All the stock street hemi motors that had chrome valve covers came with chrome PVC caps also

1969 and earlier street hemi pcv is the path of least resistance. Take one breather off tbe tube, put the pcv in the tube, run the hose as desired. The valve clips into a metal cap which sits inside the tube.

DaveR answered before I saw this, but, like everything else, the PVC system was a serious set of compromises. An adjustable PCV valve is just that. I've used them to clean up dead stock rebuilds and they are worth it every time. Unless you are so cheap it doesn't matter if you can make it better or not.

Any cam with perhaps10° or more greater .050" duration than stock has greater exhaust contamination of the chamber at overlap, and reduced idle vacuum. The amount of air admitted by the PCV is added to the air through the carburetor(s), so it affects your idle's throttle plate position w/r/t spark advance and tip-in response The Wagner allows you to adjust these factors. One less thing to worry about? Cheap.
