Looking to get rid of the draft tube. Thoughts are to plug the holes in block and weld a fitting into the side of the hump in the valley pan for the PCV valve. Anyone don this? Or is there a better way?

Previous owner did an install like you mentioned. I've seen others where the valley pan was drilled with fitting attached to the pan. Hopefully others will have some suggestions.

I tried something similar to this where I plumbed the draft tube into a vacuum port on the carb. I worked great to get rid of the fumes, but the setup acted as a massive vacuum leak and the car ran poorly.
Currently I have the draft tube and the oil filler port vented directly into the air cleaner housing and this is working out really well. No fumes what so ever.
