Picked up my 1st early A body

Are these manifolds off a particular year of Dakota? Do the flow well or what?

I wonder would they clear power steering in an early A? Might be a good option in lieue of tubular headers if they give good bang for the buck.
No particular just got to find one with an v8, they do flow well and each port flows the same direction, I dont think they will fit with power steering tho.
