I wouldn't run any less than 10 deg. on your setup... if you want, try two steps colder. I run AR3932 plugs with the 150 and 200 shot, and like 'em alot so far. Don't think I'll have to go much colder.
As for drivetrain, I run 4.30's, 28" slicks, and a Jerico and cross the 1/4 at 7000 on the 150 shot, best time in sig. I've tried the 200 twice and I'm still working on a few things to get it to hold on the big end
On the 200 shot, I ran a 6.71 @ 98 in the 1/8 tonight, but the nozzle blew out of the rubber elbow on the AFM power pipe I run. The first time I tried it, I pulled too much timing and it popped through the intake and mushroomed the K&N filter and blew the nozzle out. Launched real hard (best 60ft.)... knee high so I'm told, it's definitely the biggest wheelie I've ever done
As far as water temps go I run 170-180 before I stage and trap at around 190-200... kick on the fan and it drops right down to 180. Get to the pits and run the elec water pump w/ the fan and bring it down to 140 and head back to the staging lanes to arrive at around 160.
The clutch setup, how'd you do that exactly... I run an MSD on/off switch with 3400-6900 pills currently. I'm going to make a pedal stop and need to bypass the neutral saftey switch tomorrow. That should get me some better ET along with some other small stuff I'm doing.
Good Luck with the spray! Do keep us informed
