Could you expand on that? Do you weld the plates to the vanes? No balance issues?
Yes just cut a round plate ~1/2" larger in diameter than the vanes. Drill a 3/4" hole in the center & (3) 1/4" holes for a 6 vane on every other vane & 4 holes for an 8 vane on every other vane about halfway between the center & the perimeter, just locate em on the fattest part of the vane & have your welder MIG em. No issue with the balance as there's not enough weight there & you center the disc on the vanes & have the welds spaced every other one. The ideal vane rearward to pump clearance is .030" & vane to timing cover flat including the gasket is .040" On a SB the round plate gets welded to the vanes & on a BB you have to cut it in half & set the halves between the vanes & the pump then weld em. The anticav plate makes a world of difference.
