Best 500hp N/A spark plugs? Was just trying to see if anyone has any advise on what would be the best spark plugs to use in my 500rwhp naturally aspirated LS1? I've played around with some at different gaps, but just seems like I'm constantly changing them. Any input is appreciated.

Don't get me to lying, brother! LOL
I've always heard general rule of thumb is every 100hp over stock, or full compression point, go 1 heat range colder. When I did my heads and cam, since my compression was going to be 11.7, I DID gap my plugs @.045, as I was worried about blowing out the spark with the compression.
When I get home tuesday the TR55's are getting pulled b/c at the time thats all the local stores had around. I'm putting in the 6's and gapped at either .045 or .040. I'm, going to make some phone calls and get opinions first.
Again, I'm just regurgitating information I've read on here. Then again, isn't almost everything we do to our cars information from on here
