Offenhauser adn Holly Setup

I converted my '84 CJ-7 with a 258 over to running an Offenhauser Intake Manifold and Holly 390CFM carb. With the change, came a reduction in vacume lines. The Holly setup is a bit different than the Carter. The engine seems to run relatively fine (better than it did), however, I'm sure I don't have somethign hooked up right.

1.) At the base of the carb., facing the valve cover, there is a vacume port. What should this be running to? I currently have it blocked off.

2.) On the Offenhauser manifold, I blocked off the center port, however I saw that El Rustico has his hooked to the PCV. My PCV is currently connected to the other vacume port on the carb, facing the firewall.

Any help would be appreciated.
