Hypereutuetic pistons and nitrous??

Asked two questions in another thread:
Are 360 Magnum stock pistons hyper's as another member stated???
Are hypers more susceptible to meltdown with nitrous? I plan on taking 6-8 degrees advance out with an MSD retard along with all the other nitrous precautions. Am I begging for trouble using a 150 horse shot with stock hypers if they are indeed stock??
