My current setup is PCV in a non vented breather fitted into the oil fill hole. PCV line routed to manifold from there. My makeup air is provided via a motorcycle pleated breather at outlet of tue draft tube. It’s all kinda ugly , but it seems to work.
My revision 2 plan is similar to Tuts, in some ways.
1) PCV hardline affixed draft tube. Plug draft tube. Route line around front of engine, as sneakily as possible…to the manifold.
2) Screw-in PCV valve into manifold Tee. A valve similar to what easy 283s used. Pipe thread on one end, and hose barb on the other.
3) Makeup air provided via more or less factory method. Clean side of air cleaner to valve cover. I’d like to locate a center fill valve cover. But I might just plumb a bulkhead fitting and baffle into the side of valve cover.
