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.

BR7EF's are good. I ran the 8's in mine.

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.

So I could run the 8s if my tuner can get the tune right or should I just crab the 7s an just change the plugs when I get to the track.

my car didnt daily drive too well with the 7's, maby in the tune i dont know... if you are going to change them at the track anyway i would just get the 8's for track and maby 6's for dd

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.

**** I ran around town on 9's before. It's all in the tune buddy.

whats compression?? I wouldn't be in 7s. You are going to need 8s

if it was a stock motor on a 200 you should be running a 7 or 8. on your motor with a 200 shot you should prolly look into a 9, although a br8ef would prolly be a great middle ground imo.

and im spraying a 200 shot on a 5.3 and my gaps are .30 never had an issue with spark.

I believe my compression should be a 10:5:1 but not sure I've got to figure it out I've got .51 gaskets on none shaved patriot heads.

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?
