Plugs

[nymack66]

Question,
I pull my plugs for a check and here is the results. Plugs pictured are left to right 1234 , One and Two clearly shows some excessive oiling, I am not sure about three and four.
These are NGK Plugs gap at .40. In my opinion I will not use em again , I notice they run COLD at WOT around max 130 degrees. Reason for the oil on the plugs ?
Ferm and I discuss a while back and he recommend I go Champion Ql77jc4 gap at .35
I have since installed the champions.
I will post the results after a couple of runs.
In the mean time any thoughts on the condition of the plugs? Should I be worried ?
