    Test the old ones, then change out any bad ones. If you check the amp draw, I think you should expect 16-18 amps at first, then falling down to around 12 after they've glow for a few seconds.

    i believe the 11g's have a propensity to expand when "over-glowed" so swapping to a 60g or a quick heat brand may be good to do so you don't have to worry about exanded plugs stuck in the head.
