If they are only black on the back side i.e. the non thrust side that's from running a plug that's too hot. I've seen it many times. Back siding is usually the wrong plug.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Really? No black,but When you say back side do you mean toward the cam and why would a hot plug cause that? Running lean?
