To really inspect a plug, they have to be cut to expose all the porcelain.

they do look a little on the lean side, I recommend you get a wide band to see what your A/F ratios are at.

That's a bit lean for a blower car IMO

11.6-11.8 would be a better area

Looks a bit lean to me - not horrible, but clearly on the leaner side. You don't want to see little black dots on the insulator...that means detonation and those black dots will be pieces of your motor.
