Never run the PCV and power booster line together don't tee into the booster line at all for PCV. Route it to the front of the Rochester and leave the vacuum line to the booster alone. Go back in earlier posts and see where Denny has posted some pics on how open and closed systems work and look like. It has been a recent discussion in the past month. As for your Holley question, try to run an application where they provide a PCV port. It's the easiest way to make your system function well.
