We replaced our OEM iron manifold with an aluminum only because the OEM one was starting to crack. We went with the Offenhauser (ported and sold by Mondello) which is slightly raised from the OEM so like some mentioned like the Edelbrock, we had to modify the hatch and raise it 0.75 inches and get a lower profile air cleaner housing. We also installed Paterson's block-off kit as well. After all of that, I have not seen any huge or noticeable benefit other than possibly some better acceleration but I have no scientific way to benchmark it. I was hoping for some help with cooling, and vapor lock, which it didn't seem to help with. FWIW.
