I’m not sure what you’re planning on to remedy it, but I think some spacers from B3RE might be the least hassle.
I had a friend offset machine round slip bushings from 6061 to help valvetrain geometry on my single shaft TD rockers...see if I can get a pic tomorrow. That particular system uses a .750" rocker shaft and is 'sleeved'-up to saddle size so it was an easy modification. Many ways to skin a cat.
