vacuum lines?

i just finished my b16 swap the other day. it came with an itr manifold which has a lot of those things that the hoses plug into. the problem is the hoses are too small and i want to plug them up to prevent any vacuum leaks but idk how. should i just get some larger hoses? if i can i’ll get a picture up. thanks guys

Alright I figured it out ha. I took some plugs off my old manifold and just plugged up everything that didn’t hook up to a hose. In the end, this thread was pretty pointless lol
