think of the iridium plug as a glow plug. it will cause pre detonation "pinging"

they'll work, just not as good. the only thing good about them is they last a LONG time. but yes coppers are the best just change them every 3-5k

I tried bosch platinums once in one of my old 5.0's it ran like crap with them. I'm sure iridiums would be even worse.
