Well, you asked for it so, good work costs money. You could do it yourself. There are a few good pics on this site on different manifolds to show what works. Personally for me, it takes me a lot of time to do this work. And no offense but generally people still think similar to you where they don't want to spend the money. What has been said in this post by a few is it's likely a manifold that requires very little work as delivered, will work for your application. Some manifolds as delivered with extensive work will be the best while some out of the box will be better but lack the design and material to be 'the best'. I'd start over and ask the question; "which manifold would Moparts recommend for my application."
