Anyway OP, IMO it's possible you've got a few things going on, too much heat in the chamber, possibly a bad valve job to begin with, hard to tell in the pics but it may be a bit lean too. With that little timing it likely wouldn't detonate but could still be right on the verge. What rpm was peak power on the dyno?

and looking at the intake surface,,it looks like someone used a cookie to clean it.so my guess is the surface isn't true anymore.
