Driver's side manifold

Wondering about manifolds for my '69 dart 360 magnum. Manual steering, column shift for now but may convert to floor shift.

I am wondering whether it will be possible to run a magnum manifold on the driver's side or whether I should track down a 340 manifold. Of course the other option is to just roll with a stock 318 manifold on that side if it seems to be net the best option.
