Default Help with Spark Plug Heat Range

Hey guys, reaching out with a question that I can't seem to find the answer for from the forums yet. Suggestions would help. I haven't contacted any vendors yet. Looking to figure out suggestions for a good spark plug and the heat range I need. Currently have NGK TR6 that came with my a&a kit. I'm getting the service charging system message on and figured it couldn't hurt to change plugs because I've read of a few people having the same issue.

Car is a 2007 Z06 with 52k miles

Here's the mods that relate:
Comp cams LS7R cam (N/A cam)
PRC 285cc heads
Kooks 2" long tubes
A&A kit Ti trim V3 with 4 inch pulley
dewitts cutdown radiator
Lingenfelter 2 step. Set at 3500 on switch and 6900 as new redline.
Kenne Bell BAP
Alky Control methanol kit that comes in around 4 lbs boost

That's everything that I think relates but I may be leaving something out. It made 690 rwhp on 5.5 lbs of boost. Let me know what you suggest. Thanks guys.

Josh
