It's definitely turning as it's in a different position than it was when I took its picture 25 hours ago. Compression is 78/80. It looks exactly like it did 25 hours ago, and they were pretty hard, hot hours. All 5 other exhaust valves are completely concentric. My mechanic isn't worried about it, but he doesn't do much boreoscopy.
Here it is about 100 hours ago
I'm probably overthinking it. I'd feel better though if it was concentric.
Lap it?
Monitor it?
Stop worrying about it?
