I want to know where to hook up vacuum to it because I already have a fitting off the manifold for the booster. I don't think I should split that vacuum to the PCV system. Is there a place to pull it from the two carbs? There is another port on the carbs that pulls when throttle is opened. I don't think that's right. What do you all think?

You'll need full intake vacuum and a big enough hose to get a good gulp of the air in the crankcase every time the PCV cycles open. Your booster should have a 1-way check valve in it, so you're not going to lose vacuum to the booster as the PCV cycles.
