Default spark plugs

I am running a 572 with a 1150 holley, msd ingnition my front two plugs number 2 and 8 cylinders are black as coal and almost look wet all the other plugs are burning fine. I also am losing almost a second on time. I would appreciate the input. Hal

Maybe an intake seal problem.. Could be sucking oil through the gasket...

You can also do a leak down test on those cyds also...
