I would recommend a br7ef for a 200 Hp shot and it will still be a plug that you can daily drive without any problems. Also I would gap them to around .32-.35.

If your motor made 530 rwhp and you are adding a 200 rwhp shot we are talking about over 700 rwhp on a ls1. I would run at least a #8, MINIMUM!
Honestly, for my liking it would have a #9 in it. There is more than one way to skin a cat but i prefer the safest way. You can't daily drive on 8s or 9s however without tune adjustment.

If you don't mind swapping the plugs just run the 8s when you get to the track. Even at 500 plus rwhp NA I would be on nothing hotter than a 6 NA.

Have you been running a smaller shot already? What plug did you have the best luck with then? If you just put nitrous on start smaller and work your way up. I would suggest a 7 up to 175 shot and a 8 when you get to a 200. Also keep the timing low and work your way up. What fuel are you running?
