Is this the intake manifold vacuum?

Ok, so rather than the first pic where I'm using the vacuum tree potentially to connect to the brake booster. With this pic am I better off capping the circled part at the valve cover and rerouting that line from the carb to the brake booster? I finally got my hard lines in and the brakes bled! Last step is to get the vacuum line setup and determine if I have enough vacuum to avoid an electric vacuum pump. I feel pretty good about it given it's the stock cam though. Thanks for the help!
