I don't know if anyone has done a useful series of tests, but getting the exhaust to flow easily all the way is a smart way to make power. A good exhaust manifold would be a nice complement to your current mods. If you want to spend money, there's a guy that will make a nice tubular steel header where the headers turn down, u-turn so the faces the bottom of the hood.
