Obviously, this is not exhaustive, as there are loads of other potential headsculpts out there (especially some newer ones that aren't even available yet). I've also limited the list to sculpts that are (or once were) more widely available, and for now I've omitted custom sculpts. Some of these heads also only go with the larger s25b type, while some go with both. Likewise, some have skintones that may not match tbleague bodies. I'll try to specify where possible.
Note also that while there are several other petite Tbleague bodies available now (the seamless ankle teen body, the anime body, the recently announced small bust body, etc), this thread is specifically for the s24a/s25b and s26a/s27b bodies. These are the ones I have the most personal experience with and which I've collected the most heads for. While there may indeed be some overlap between the headsculpts that fit these and the others, I'm not able to fully confirm that information.
Others are welcome to suggest additional headsculpts that work with these two body types. I intend to continually update this list as we go along.
