TR6 question??
Proper tuning and proper parts is the key, its not one or another. You can have cold plugs and shitty lean tune and still blow a motor and you can have a decent tune and stock plugs and still melt a plug. Im sure you can get away with stock plugs for a little bit but why even risk it??
If you search around here there are instances of guys running stock heat range plugs and ruining their engines on spray.

I run TR7's @ .035 with a powerglide, 4.10's and 5500 stall on the street
no problems driving on the street at all Nick

i didnt say i wasnt going to listen. i will be running the TR6. i was just trying to see if someone knew something i didnt about the tuning becase i am unfamiliar with what all can be done through tuning.
on a side note the only problem ive had with my ngk's is running a shot and torco, they dont really seem to like each other
