Hedman 78050 in a 67 Cuda..anyone use them?

In the process of building a new engine in the 67, and am toying with the idea of getting rid of the stock exhaust manifolds. Really don't have the money for TTI's, and have had fit problems and ground clearance problems with some hedders in the past. Anyone had any experience with these ? I know they're not coated, but I can take them into our shop and paint them with hi-temp and bake them on. Any ideas would be appreciated.. Larry
