Im no expert but it doesnt look like the soot ring around the base is all the way around on any of the the plugs. That means not enough fuel from what Ive read.

Are the plugs okay to run again or should I toss them. It's hard to find these where I live. I have one extra I throw in #8
Is my .033 Gap okay?

Gap is fine.
If the plugs are new you can keep them for later use but for tuning purposes you need to throw a fresh set in. I suggest cutting the threads to verify the fuel ring as well.

I'll pull the timing. I checked my tune and I had a leaner VE Table in the car. I went back to my table that is a tad richer.

I would throw that plug in #7 check that one as it seems to be the hottest ... so tune off of it.
Good luck!

I'm trying to get a handle on reading plugs as well. Can someone edit the photo's posted here with a few notes of what would make the plug a perfect plug? For example a line acrross where Timing would be perfect. or the plugs need to have more color here or there...........
I keep reading "color is at the half-way point on the strap" for timing. Well to me those plugs look to be just that. So I must not be completely understanding. Also is the jetting slightly lean because the Black ring didn't go all the way around the base? they have a few light colored areas yet.
Just looking for something a little more than "Yep pull 3-4 degrees".

Part of the pulling the extra timing is it simply to be safe. Guys like ATV run the same gas, check plugs every pass, and in general have a very good handle on the tuneup. They are able to tune a little more aggressive on their personal car. With a daily driver like Sarge's something as simple as gas with more ethanol or even spraying longer could hurt the car if he was tuned to aggressive.

Id pull 3-4* make another 1/8th mile hit, then cut the plug and see how the fuel ring looks. I wouldn't mess with the fuel until you made a pull with a little more timing pulled.
