I cleaned up the flashing in the ports and gasket matched about 1/2" in. I didn't touch the short radius as everything I've read (including Herr Don's) showed no improvement in doing so. The valve guides were also blended. I don't know if this will help, but Mopar had cast some rough guides in the bowls.
