Is much content in the Classic Goosebumps reprints changed besides the cover?

I’ve been buying the Goosebumps books on my Kobo, but many are the Classic reprints with modernized covers, so I’ve been changing them back to the original covers using Calibre. Has the text in these reprints been changed much besides the tombstones in Dead House? (I know the actual originals have been uploaded to Archive, but I prefer to support the author)
