Hey guys just curious if you guys have had a spark plug look like detonation got it from making a pass on a low bottle? Made some passes and last on was bottle was gone and mph/et was way off and when I got home to change plugs I noticed number 5 plug looked bad but was the only one. No different tune then before with no problems before. I did drive the car around on the plugs later that night with N/A timing on them so it had motor time on it also. Sbf 175hp shot with 116 in the standalone and a mix of 93/116 in tank with timing locked at 25*. Ill post a pic later

One thing that might be worth doing since its free and easy, is OHMing the wires and see if 5 is seeing a weak spark?

No anti seize so probably a little oil. Didnt think of it untill you said the wires but that wires boot is right under the valve cover breather and oil drips right on it... right where the plug wire runs into the boot.
