Here is something to consider regarding the flush. My ECT/OT numbers were very close to yours. I decided not to use VC9 or Cascade to clean the system. I flushed it like crazy with a garden hose, pulled both block drains multiple times, ran it a bunch without the thermostat in. I then flushed it a couple of times with distilled water, then topped off with Rotella ELC. That was at least 10K miles ago and my temps have not changed at all.
