Spark plug colour not right

Ok hope the pics uploaded OK. The plugs are only about 500 mile old. Plug 6 and 8 are alot dirty than the others. I'm trying to get to the bottom of this limp mod when it's at full power. It's bm3 mapped as well...

I also think the gasket is going at there was a little oil in the plug well..

Any idea why this is happening
