I'm no expert, but those plugs do look rather dark. The strap is a nice ash though, so maybe it's just a positive cylinder pressure thing? Safe, slightly rich, AFR I'd guess.

Also interested in where the front end is going. I'm not a fan of cowl hoods, although I know yours had function to it and I can always appreciate that.
