My opinion is biased, but if it's those ultra shorty block huggers or manifolds I'll take the manifolds every time. Those headers gain you nothing, but give you all the drawbacks of having headers. If you're gonna deal with the pain in the ass factor of headers, get some good quality long tube headers.
My 2 cents (and I'll add that I'm intentionally keeping the cast iron manifolds on my current 350)
