You are gonna hear a lot of TR6 responses here, personally my truck ran like crap with TR6's, the stockers are in it and still look perfect with:

Steig ported eaton
6# lower
C&L intake
Accufab TB

The KB should run cooler than mine does...

youll need something colder then the TR6 for that one

I would think the NGK BR7EF's would be the way to go, I was thinking of going to those when the time comes. The TR6's have been flawless for me, gapped at .036" 24K miles on them.
