FWIW, I use a large sheet metal Y-fitting and run both the PCV and the power brake vaccum hose off a single large hose bib to an SVO single plane intake. It seems that the 'flow' thru the vacuum connection is low enough that separate hoses for PCV and brake booster are unnecessary and in any case will ultimately connect to the same source- the intake plenum. I assume that a single large hose bib on other Holleys (my tuner double-pumper has no large connections at all) would work equally well. At any rate its worked this way on our car without a hitch since 1991....
