V8 into 64 Dart Swap, Exhaust Manifold Clarification needed

Hello,

Placing in my 64 Dart a mid 70s 318 and 904 tranny.

I see talk about exhaust manifolds and that the driver's side is not a standard one. Is that exhaust manifold only NEEDED with power steering?

My car has manual steering and just looking to clarify what I have to get for exhaust manifolds to make this swap work.

Appreciate the help. Thanks.
