Spark plug gap for 2.8"

Spark plug gap for 2.8"
Like the title says, I'm running NGK 1 step colder plugs(heat range 6). What gap should I change them too? They are iridium, so I know I have to be careful when gapping them.
Mods:
2.8" pulley
60lb injectors
dual pass
frozenboost dual core h/e
knn intake
pacesetter header
modified lsj dp
Megan catback(oval muffler w/magnaflow tip)
ttr poly tranny bushings
ttr poly engine mount
working with vince on my tune, here's what he said:
"There are two things happening here.
*
1)****** It’s still too rich
2)****** The knock sensors are picking up noise the ECM thinks is spark knock and its sending the timing into the basement
*
#2 could be because of #1 though (if it is real knock).*"
I have double checked every wire, gasket and bolt. Mechanical it's all good to go. Just Need to figure this spark knock.

Are you running LFR6A-11 like alot of other boosted 2.2/2.4's? If so, those are copper plugs. Also, mine lasted 20k before i replaced as preventative maintenance.
edit: yea i can't read apparently as you said iridium in first post! Maybe switch to the coppers I mentioned then, which are also 6 heat range.
