I see on Lethal's website two TR6 plugs, the iridium, and the v-power. I see a lot of people running the TR6 but I was wondering which one of these it is? The iridiums are $40 more, is it worth the extra price? What's the proper gap for a 2.8" pulley setup, .030-.032" or so?

You'll get opinions both ways. Many prefer to use the regular NGKs and save the money since they change plugs at least once a year anyway. Also, the iridium plugs are more prone to damage, especially when attempting to adjust the gap. I personally used iridium plugs are liked them, but they were the Densos. Gapped at .034 by the way.
Copper at .032
copper at .032" and for 2 bucks a pop you can tbeat them.

Are you sure that's the item number? When I went to the parts store the number that showed up was 4477
Got the same ones but gapped at .28 with a ported 2.76.
Yes, the 4177's are the correct ones.
