I have converted several Y-blocks to PCV systems, getting rid of the draft tubes. In a few cases I blocked the draft tubes off when I installed the PCV, I did this to retain the original look of the engine.
With the installation of a good PCV system, you will be amazed how clean the engine and engine compartment will be because the oil leakage from the fill pipe, etc., is eliminated.
The '63-64 292's in the Ford trucks had a really neat PCV system, that is what I generally use when I convert a Y-block to a PCV system...
