Hey Aaron,
glad to hear the VC is now working fine!
To remove all Google Font API references, you can simply remove lines 30-75 from the header-functions.php file; I’ve prepared the file with removed calls for you, can be downloaded here. In case some other parts of the script start slowing down the website when viewed from China, please let me know, we’ll think of a way to solve that too.
Sincerely,
