I went with Gardner, however...

The angle of the "cup" to the drivers manifold was off and leaked. Since the HEMI head pipe mount is that rounded "ball and cup" type joint, it still connected, but barely. I eventually removed the system, cut out a slight wedge, bent it into place and welded it into a better angle. I still had to use a hand made gasket and use some gasket sealer to stop the "tic-tic-tic...". Gardner claimed it was my use of repop manifolds. Maybe the leak was due to the repop but not the off angle. Other than that, very nice materials and construction. Looks very original.
