If they're Hepolite replacement rings, the top ring is usually a "Ridge Dodger" style ring with a step on the outside of the ring so that the new ring never actually reaches the ridge.
If I didn't have a ridge reamer, I'd be inclined to use a sharp bearing scraper to blend out the the ridge once the glaze has been removed.
I always check ring gaps when I rebuild an engine, only takes a few minutes, stick the piston 'upside down' down the bore to ensure the ring isn't crooked which would exaggerate the gap.
