Confirming spark plug choice

Hi all. I recently bought a 2011 V (MT) with about 98k miles. After spending more time driving it, I decided I should check/replace the plugs and probably wires. I’ve searched the forum and read a lot of input n spark plug choices. I think I’ve settled in on TR7ix replacements (which seem to be part number 3690). Before I pull the trigger, I thought I’d post this to see if anyone has a strong opinion against it. I know a common response is “ask your tuner,” but I don’t have a tuner.

I pulled 2 of the existing plugs. They are Br7EFs and are only gapped about 0.020”. They are also a bit dark with some carbon build up. So I was thinking the TR7s gapped at 0.030” would be a move in the right direction.

Mod list:
Tick performance Stage 2 blower cam kit
Tick/pac .660 valve springs/titanium retainers
7.400 pushrod set
GM timing chain and gm dampner ls2
Ported and blueprinted oil pump
Tick cam swap gasket kit
3 bolt cam conversion kit
ARP crank pulley bolt
Morel 5315 lifters
Ls9 head gaskets
ARP head bolts
2.5 upper pulley
Air raid intake
1000cc injectors
160 thermostat
Stainless works exhaust
Green gates belt
Reinforced brick
Solid isolator
AEM wideband

Thanks in advance for your thoughts. I’ll take input on good wires too!!
