Also make sure that your drums haven't begun to flare ("bell mouth").
This was a problem on early Porsche drums, because they didn't have sufficient support on the open end.
The shoes will wear and deflect somewhat to make full contact, but the brake performance suffers.
The 60s 356B drums were much better in this respect.
If you look at the photos posted on CH Topping's Yelp page, you'll see a dozen 356 drums on the floor, including a set of Rudge drums.
Another photo shows a heavily finned RSK Spyder drum on their lathe. They do much of the vintage Porsche work in SoCal...
