The Dakota headers are a good choice.
Another really good option is the manifolds from a 5.2/5.9 Magnum, they flow really well, reportedly on par with the early 340 manifolds, which are highly regarded for flow.
The 92-93 versions have a slightly larger outlet from the later ones.
But either size would be sufficient for a stock LA.
Due to the larger outlet, the early manifolds reportedly fetch a premium.
They have an EGR port that needs blocked, though. (visible at the rear of the passenger manifold shown here, it's the flat spot pointing upward)
And be aware, there are Jeep 360 manifolds avaialble in the Magnum era too. (bottom pic)
They are Mopar 360 pieces, and they bolt on, but the exits are in different locations. I don't recall any reports of how those fit in a car.
