2 sets of Dakota V8 manifolds

My understanding is that these bolt right up to the LA engines. From what I have found they flow as well as most 340 manifolds & are way less expensive. They apparently will not work on an early A-body ('62-'66) with power steering, which I have, so I do not need them. I was hoping they would fit but it looks like they do not, at least without some major mods to the manifolds & car. I already have a set of spitfires so if I go back to manual steering I will use those. Here are a couple links with more info:
