Not sure if I understood your problem....
Are you saying that where the skins bend (where the mouth of the drum goes) is too big for the second set of congas? If so, then your other set is simply not the same size and dimensions.
Regardless, one thing you could do is re-wet the skins upside down in about 2 inches of water (so you don't wet the whole head thus excluding where the ring is) and re-mount. Leave a bit of pressure on the lugs so the head can re-adjust to the new borders. It might stretch your head down a bit more but you'll get them to snuggle the new drums better.
Hope this helps some.
