i'm putting the 99-00 manifold on a z6. upon searching i find i need to plug the air injection hole. am i to understand this as the 4 holes at each injector. the port in the center is sealed off with the gasket so i assume it's these creating my leak? will jb weld seal them properly?

 

Yes and yes.

 

thank you. upon more search i found this. thanks for the quick reply. mods delete if needed.
