Do you already have the headers or stock manifolds? 340's were pretty spunky from the factory with the exhaust manifolds, so if you aren't going to race it but just enjoy some spirited driving occasionally, stock manifolds will be more than adequate.
It had Hooker headers when I got it. They were beat all to hell and are now defunct. I don't have the stock manifolds. Will have to locate a set. Know anything about repops?
