nitrous oxide on a hypereutectic pistons

I have the sheet that came with the pistons, I gaped them to what it said. I just thought I had set them to .018. Thats what I'm used to setting regular pistons at. But if it blows, I've got a 1999 magnum with 90,000 miles on it hanging on a stand that I've been wanting to build anyway. I guess I'll use forged pistons in it. Thanks for the info guys I guess well find out in a couple of weeks. I'll take it to test and tune for a couple of weeks and break it in some, before i put the gas to it. Thanks for the info guys
