You've done 18 pulls and now all of a sudden you're an expert?

Image how much more power it will make when you you get the cylinder pressure up high enough to tan the plugs......

18 pulls on this engine slick. You haven’t explained why more color on the plug is losing power.

It can’t be the carbs are too big because they would be small on a 380 inch engine.

It can’t be the fuel isn’t atomized well because I’ve seen that and this ain’t it.

There you have it. You don’t have a clue what you are talking about. And you talk a lot.
