[Healeys] spark plugs

[I Erbs]

> On the subject of plugs,

I have read archives about plug temps, but not really much info on a
formula for figuring out how to determine which plug is best fro a specific
engine.
 I have a BT7 with 2" carbs +.40 bore, hotter cam and it has been balanced,
What champion/NGK plug should I use? Do I use a std. plug or a hotter plug?
A part # would be great.
Thanks
