Ok, you have to lose those plugs. That giant assed ground wire hanging out there getting red hot isn’t helping anything.
In fact, that plug is not only the wrong brand, it’s the wrong design. IIRC a 452 head takes a J series Champion which is a 5/8 reach, 13/16 hex gasket plug, not a tapered seat like that.
It could be later BB heads went to that tapered seat plug but I don’t remember that.
I’m not saying anything else until you get the right plug in it and go beat on it a bit.
But I will say this. If I had to just look at those plugs I’d say they are too damn hot, you are far from lean anywhere and you have an oil control issue.
It’s hard to fix a tune up when the plugs are that wrong.
