Clearancing adjustable rocker to spring retainer question.

I don't recommend that, because 99.9% of the time, the rocker shafts need relocating. Mike at B3 Racing Engines can help you determine that. @B3RE I tagged him, so maybe he'll chime in.
Thank RRR. The interference is primarily slop/rough spots from the casting process. Everything is lining up nicely. Appreciate the input as always.
