61 Impala

So I took off my intake manifold to clean it and paint it. New gaskets all around and that's all that changed. Now my idle is up around 2,000 RPM and I have no idea why. My air filter was really dirty, but the throttle body and intake manifold inside wasn't bad at all. So, 1) why would the idle change, and 2) how do I change the idle down? Thanks in advance.

Vacuum leak somewhere?

Yup, vacuum leak. Fixed, thanks Big Bomber!
