i think you will find with most LS1's over 20-30k your going to find one or two plugs with no platinum tip. I know they tend to fall off. I have heard NOS is a contributer to this as well. Your car was running on 8 cylinders, if anything you were getting more of a spark out of that plug as platinum is not a good conductor of electrical current. platinum tips are only on there because (if they dont fall off) platinum is very durable. The bigger the gap, more fuel is burned but the worse the idle, i have even cut the side electrodes off all my plugs in the gas race car on one occasion at the advise of a buddy and it ran the same.
