Plug read opinion
Too much fuel, and too much ignition timing.
And how are people getting to the conclusion that being rich lifts ring lands, and over timing burns pistons? Ridiculous assessments. Too much timing and your ring lands are gone, too lean and you have a melted piston.
Anyone that disagrees, I would like to hear your explanation that shows otherwise.
Cheers.

lol someones been on YB too much.
fuel gets between the ring lands? explain the thought process other than "fuel seeps through the rings and then ignites and breaks a ringland".
Doesn't happen, timing is the reason your engine is breaking ringlands and the amount of fuel present either slows or speeds up the flame front. The other silent killer is predetonation, MUCH different from knock. A plug with a good heat range, and a good quench in your engine will ease pre-det.

Pump Fuel "Stoic" Hi Square, the TERM RICH/LEAN = Above Stioc/Below Stoic for the fuel used.
THUS below 14.77 AFR "pump gas" IS RICH.
YES too much fuel WILL Melt a piston faster and with too LITTLE Spark Advance.
The REPORT of a high EGT WILL BE FOUND.
We operate engines at 18:1 AFR for years at WOT with a safe (correct) Spark Instant.
GM runs Truck Calibrations with little Spark Advance (the correct advance) at a Stoichiometric AFR for Torque Limitation.
The best bet is to use/but/fit an EGT meter.
Many GOOD NOS (N2O) calibrations can observe lower than 1000F EGT when at WOT with "chill".

Not to define rich or lean when compared to a stoichiometric value.
