ODD Spark plug coloring

Guy's as some of you know late last year I picked up an new dragster for my kids and have made maybe 4 runs do to a lot of weather problems this year. I pulled the spark plugs and notice that the number 2 and 6 plugs are fairly WHITE? Knowing the plugs were older I placed a new set of AR52's in it and hope the weather holds out this Saturday for a race we have to see if it happens again. This is a 556 A460 headed deal with an off the shelf Lunati cam ( )

IMO, white is not bad as long there's a bit of "straw color" on the lower portion of the porcelain near the jacket. If you have doubt's of the lighter condition of the spark plug's porcelain, add a main jet. A bit too much fuel sure won't harm the engine like a bit less will! It could be a distribution issue with the intake tract .... I think...

Lem has a good crystal ball for looking into the plug's eye!
