I will have SLP 85mm MAF, FAST 90/90, Stage 2 Patriot heads, LT's/ORY, big cam, 160* therm, Volant Cold air intake.

Would NGK T6's work for this?

The T6's are more for Nitrous. Stick with the 55's.

What effect does running a colder plug have on the chambers? A colder plug will cause less detonation on a higher compression chamber....because it runs colder? What setup do you have that entails you to be running a colder plug? Wouldn't a colder plug be in everyones best interest because a colder plug means less heat in the chamber, and that means the A/F mixture will only ignite with the spark? Isn't this ideal?

Thanks

too cold of a plug wont ignite the mixture well enough and will run like **** in the low end. a plug too hot can preignite the mixture causing knock.
