Anyone know how to read plugs?

[Tyson Varosyan]

Just pulled these from my friend's NA car and they dont look right to me.
There is no "black pepper" on the inside stem, but the electrode is way worn
down and has that white crud all over it. Too hot?

Please see http://www.up-times.com/car/plugs.jpg for the picture of the
plugs.

Thanks,
