I would not use Iridium on FI applications.

Just use the Standard Plug....
Set the gap to about .030

And you will be ready to rock and roll.

We normally run TR55 plugs on a N/A head and cam motor. The TR6s are a step colder from the TR55s.

You can gap them there, though you will not loose HP by gapping them just slightly smaller. The range most stick to is 30-35.

Your Coil Packs will thank you, and you will have even less chance of spark blow out, on the high end, when the cyl pressure rises.
