Need a part for my manifold

[Gnarkill]

I have a edelbrock performer 351W manifold. There is a hole to the left of the carb on the manifold. Someone told me that it might be for a heat choke, but i have a manual one. I need to block off that hole, But i dont know what to but that will block it off. Is there a internet site?? Thanks, Gnarkill
