B&M Flex-plate

Looking for some advice here. I purchased this flex-plate many years ago for my engine (426 wedge, 440 cast crank, 6-bolts, damper number 3577785 [USE WITH 440 CAST CRANK ONLY], externally balanced, no weights on the converter. Should I grind of the weight welded onto the flex-plate, or leave it? I have no idea.

Thanks
