is an iridium plug the way to go? or does it make a difference

An iridium spark plug has a smaller electrode, so it requires less energy to spark. Theoretically, it can handle a higher compression at a larger gap.

Iridium is also very hard, which means less gap growth, and longer spark-plug life.
