I have had to notch every B1 cover we have run to clear the T&D rockers. The one exception being the old style cast B1 covers that they no longer made, they made a short and tall version of those FWIW.

I am in need of two sets of B1 sheet metal covers once again as we have a couple new engines wrapping up soon. Love to hear more about the ones you are doing.
