Looking at Tim's page above, the '54 version would be superior to the much newer design, in terms of providing clean air for the PCV system. In the '54 design, the air is drawn from the filtered side (center of air cleaner), whereas the more modern versions pull unfiltered air from the side of the air cleaner.
