my general spark plug info from my website (temporarily mirrored at hlh0501.straynet.com ):
"1step colder NGK Copper BKR6E
2step colder NGK Copper BKR7E
1step colder NGK Iridium BKR-6EIX
2step colder NGK Iridium BKR-7EIX

.0433 stock gap
-subtract ~.004" for every 50 hp over stock"

so, according to that I would go to an ~.029 gap ..
btw i saw your car in that vid of all the max's , everything is looking good! get on the dyno
