Thanks for pics. Did you go through wheel wells?
Those plugs are shot, coated with deposits, probably ash. Electrodes don't look too burned, though. How many miles?
Different plug coatings usually indicate unequal AFR. Perhaps end air induction biases foward cylinders for more accurate AFR mixture?
Chevy used to have centered induction, so corner cylinders ran rich.
To have all 8 run perfect would require a MAP sensor in each cylinder induction tube, and AFR signal doe each fuel injector. Big bucks.
