Hey guys, just upgrading my inake manifold to the Golden Eagle one for my built ls/vtec motor. Couple questions-- I know the heater core needs to be replaced, but there are a couple more nipples and a large line coming off the back of it, that i'm not sure where it goes to. If anyone has any diagrams, or pictures, that'd be great.

 

do u have any pictures of what you are referring to?? just thought I would ask.
