On my 440 in the Demon I use an M/E Wagner adjustable pcv with a hose off the other bank to the air cleaner base to mimic the factory setup. The key is the pcv is adjustable as any upgrades will change the vacuum characteristics of the engine. The breather and hose comes in play when the pcv isn’t operating. The pcv is pricey but in my opinion when you drop money into an engine what’s a few bucks for something that has benefits. They have some good reading on their site. As far as a vacuum pump I can’t answer. The header evacuations may not have enough flow to work correctly on a street car. But someone with more knowledge may be more informative.
