Thanks for the opinions. Those 3 photos are of the same 2 plugs from different angles. Sorry I didn't mention that

Car is never warmed up, been started all winter on weekends and then shut off after 10 minutes

Driven 10 miles, maybe, per month this winter

These facts combined, are those plugs not used enough to determine the tuning?

Also, there's a 574s plug with a resistor and a 576s as well. Ones hotter than the other. I wanted to try a resistor plug with my setup. Yes, no? MSD 6, 38' locked out timing but computer controlled 20' timing at idle, MSD coil + wires, 9.7:1 compression

EDIT: Any odd metals that might be on the 2 plugs shown are from crap thats on the work bench.
