I run BCP7ES's (#5030) in my Eddie-headed 496. I would foul out with anything 6 or under. 7's stayed NICE and clean, looking perfect after 21 dyno pulls.
11.33 @ 118.46 on motor
10.75 @ 125.35 w/ a little spray

The higher the number the colder the plug though?

Those NGK 11's are way to cold my friend. Unless you are running 14:1 and about 800hp!
Lower the Number on NGK= Hotter
Higher the Number Champion= Hotter
Be careful what people say on here. We have a mostly street driven 11:1 440 with Aluminum heads and it runs BCP6ES. I have "the colder" 7's for the strip.
You have to know your compression and have good oil/blow by management.
