Not good, obviously.

So in a roundabout way, is it possible the lsn was too lean and causing the engine to overheat? I'm kinda sure it wasn't the high speed being lean 'cause I was around 4 turns out from bottom, I'm just out of ideas on what it could be.

Check to see if the HSN is working its was out, I had this problem with mine. Also check for airleaks, tubing, tank etc. This can also make the engine lean out and run higher temps. Or if something is binding and causing the engine to work harder, brakes, diffs, bearings, cvds, etc.
