Autolite 104's in copper and you need a tune to run it properly. You will be changing plugs every 15-20k when you use copper. 75 shot is fine if tuned properly. I used the ZEX Dry Kit and had great results with it. ZEX is the shit if you ask me. People talk about wet vs dry and sure there are advantages to wet, but if done right the dry kit is perfect for 100 and under shots imo
