Thank you for the response

I believe a couple of guys on here have done it by mounting the PCV valve in the valley under the intake and running some plumbing. I have no idea how effective it is.
Looking at the first illustration, won't the direction of the TEAL arrows go the opposite way, as the Vacuum at the carburetor base be going In/Down the intake into the cylinders?
