You're right about the gap being .044. But, if you're using OEM NGK's or Denso's, they have the dual electrodes and the gap is preset from the factory. Gaping the plugs is not necessary or recommended.

If you gap them you will ruin them. The arc between each ground has to be exactly the same. If you gap them, it will only create a spark between one ground and the electrode instead of between both grounds and the electrode. It will be like running normal spark plugs.

Your not suppose to gap platinum or iridium plugs because it will ruin the platinum coating on the tip of the plug. I know for iridium plugs you don't need to gap them because they come pregapped and if you do gap them you also might damage the iridium tip. Also you don't need to service Iridium plugs for 5 years.

Thanks for the info.
BTW, I will always play it safe and use OEM spark plugs and nothing else and if I take out the spark plugs to service the engine and put them back in, I always put them in the same cylinder.
