yes. You are correct. A pleated paper filter is used. This set up can be used on a Chevy as well. I usually see these on the military 270's and 302's but have seen them used on 228's etc - for the pre-war trucks and later.
This type of draft tube and filter set up can be found on Ebay. I believe there are a couple on there now.
Locating an elbow or making an elbow for the valve cover should not be too difficult. One of my 261's has a home-made elbow that was tacked to a small metal backing plate, that was then tacked to the underside off the valve cover. A rubber line was then routed to the intake, that was drilled and tapped for a fitting and PCV valve. It works although not the prettiest I have seen.
Seems to make sense.
original filters can be found easy enough with a little patience and perseverance.
