Getting a little “Moparish” in my garage

Actually looking at the exhaust manifolds I believe they’re the same as the 340’s not sure if they were swapped or if that’s just the way they’re supposed to be. Ohh before I forget if my cuda was a factory 1969 340 car does that make it a formula s or am I mistaken?? I’m still learning about these older mopars sorry for the newb questions
