Default Spark Plugs Suggestions

I am trying to figure out what spark plugs to go with on my '01 Z28, it has an MS4 cam, PRC Stage 1 LS6 heads and headers. Someone suggested going with the TR6 spark plugs and was wondering what you guys think about it? Should I go with the TR6 plugs, or what do you guys suggest/run?

Most guys on here use ngk tr55 on n/a motors and tr6 on blower motors.The tr55 is slightly hotter than the tr6.I would use the tr55,but you can also use the tr6.

Will running the Tr6 spark plugs damage the engine?

The reason why I am looking for a good set is because I just installed the heads and cam on the car and am about to get it tuned and want to run a good set of plugs. I'll also be running a set of 42# injectors.

I have used both tr55 and tr6 in my t/a.You can use tr6's if you like.I don't think you will have any problems.

^I''ve also been using them on my truck and I don't have any problems with them.. Truck passed emissions with FLYING colors! -1995 Ford F-150, bone stock.

A lot of people bash the e3's, but I'd like to try them on the Camaro.

I was actually at the performance warehouse trade show in portland last spring and talked to one of the e3 reps and he really stressed the point that the plugs create a more uniform and complete burn of the air fuel mixture inside the combustion chamber becuase of the the arch design instead of one, causing increased MPG and performance. Ive been an NGK guy through and through and they have never let me down, but ive heard good things about these e3's.
their is really no need to run the tr6's becuase you are not running nitrous or a blower. they run that colder plugs to protect from detonation becuase of the increased temperature inside the chamber]
