Hard to tell from the pic, but they look to be a little black, which would lead me to believe that you're running rich, or the plugs aren't the right one's for your setup. Typically a good burning plug would be light tan/brown colored.

4) Spark Plugs - Change out those stock spark plugs with new ones to restore any lost power. Brands that most tend to go with are either Copper Core Autolites or NGK's. They range as follows in order from hottest to coldest plugs...remember...you want the hottest spark you can get away with...so running a super cold plug on a larger pulley to combat knock isn't the best plan...OEM replacement ACDelco's, AL606's, and AL605's are basically for stock cars or very small bolt-ons still running the stock S/C Pulley or modded N/A guys...you want to keep a hot spark. NGKTR55/AL104's for your 3.4" Setup, TR6's are a tad cooler...best used around the 3.25" pulley area, and AL103's...are for the extreme supercharged application...3.0" pulley or lower. Here is a picture to reference the firing order and the correct coil number if yours aren't numbered or you just need a quick reference picture: http://i33.photobucket.com/albums/d6.../plugwires.jpg
