Best Spark Plugs for me?

What would you guys recommend on spark plugs? I need some new plugs and not sure what to get. I'm leaning towards the NGK TR55's but have seen the NGK TR55 Iridium IX plugs and read they are supposed to be better plugs. What do you guys think? I'm running around 11-11.5:1 compression and alot of the time run octane booster. Don't know if that makes any difference on what plugs you'd recommend or not, lol.

being as how you aren't stock i would probably go with the slightly cooler TR6's and i wouldn't go with the iridiums either because of the high compression they can lead to detonation, just the standard copper cored plugs will work beautifully

I have ran the TR-55's in my heads/cam LT1 and my stock LS1 and TR-6's in the LS1 for spray, but it runs fine NA...

I would think either of those would work well for you.
