Schumacher headers, grinding boss on block
My 400 has one of the "extra" bosses on the block that needs to be ground down to make clearance for Schumacher headers. Does anyone know if there's a limit on how far I can grind it before going too far? Or can I just go crazy grinding to make sure there's plenty of room?
It looks like it should be solid, but I would be hating life if I ground a hole in the side of my block.
This is a photo of the boss/header interference that I stole off the web:
