Orangish Hue on Spark Plugs

O.k., after some jetting on my Eddy Headed 408, 950 Qf, got it pretty dam sweet for the street. Then I pull my spark plugs, and they have an orangish color to them. Is this coolant? The car runs AWESOME! No miss, 12.1 @113 this summer without tuning, great manners. I did use Cometic gaskets, which I thought were good. Do I have coolant getting in the combustion chambers? I added a bottle of Octane boost the other day. Could it be the sulphur in some of the fuel? I live in North Texas. Any ideas or suggestions welcome.
