Are you running a dual plane? If yes, then,Check the two center plugs on the other side and compare to 2 and 8. If they are all on the same side of the carb, maybe it means something,IDK.
Drivers side bank is all good as far as plugs go. I really think based on the permatex ‘reduction’ and the vacuum leak, and the oil straw, that’s where all of my issues are coming from. Hard to say otherwise until that’s all fixed.
