It was interesting pulling them back out to regap after about 30 minutes of running. Not only were they still clean, they looked brand new (keep in mind this was on straight E85). You literally couldn't tell they had been run except that they were hot.

pull them again in a few weeks to see if they have opened at all. Curious.
