Spark Plugs

[Speed Racer]

Okay guys now that you have got me straightened out on the Bassani's?!? next question:
Spark Plugs
As when they are going to be pulling my motor apart for the Roe S/C upgrade I read somewhere we need to be running a lower temp plug to combat pre ignition. Which plug would be best for power and longevity? Do I need to gap em? I have read the threads but there is no farogne conclusion. The NGK plugs were the ones most often mentioned.
Thanks guys

I had been recomended to run Champion RC12ECC, NGK 5155, Bosch 7527 or Denso Iridium 1K16 for a heat range lower. I am not running s/c, but lower temp. Did not have a gapping that I know they should be at, but that was what I was told was right. I'm interested to know also.
