In short the question is if I should leave headroom on the uploaded high resolution wav files (-1dbfs) to prevent clipping from the transcoding process. What is the best way to guarantee unclipped files on soundcloud without sacrificing loudness? Thanks in advance-

There currently is no normalisation or loudness metering done. All of our users' uploads get encoded to 128kbps mp3 audio files, however when they allow for others to download their tracks, the downloadable file will be the exact same file the creator uploaded. This might be of interest for you (I guess if you're a mastering engineer, you've come across similar articles before).
Other then that, there is a longer discussion on the matter here on our help forum. It's been forwarded to the relevant team for reference.
All the best
