Break in problem...

UPDATE: Timing is set to 34 degrees, no more red hot manifolds (Thanks!). With the thermostat removed, I got 12 minutes of run time until I had to shut down due to temperature running up to 210. It was a cooler night tonight and I had a large electric house fan blowing in addition to my Spal pusher fan, but the car is still in the garage (all doors open with a small breeze blowing through) with no brakes, so I can't move it outside. On the temperature climb, it paused around 195 for a couple minutes, and I thought I had it whooped. Then it gradually started climbing again and slowed around 200 for a bit and then began climbing again. I know doing the break-in in my garage is not ideal, but its how I had to do it, as I am having to redesign my MC/Booster setup. Do you think it will behave like it should when I'm driving, or this going to be one of those bass turds that doesn't like to cool? My radiator is a brand new aluminum three row Champion.
