Damn engine looks like u been running Kerosene Lamp oil in it for only having 150 miles on it. Loose valve guide clearance or some crappy valve stem seals.

I got nothing else to add so I'm just gonna shut up and watch from sidelines.

Detonation?

I wish I had access to a test stand. That would be ideal!
