Default E85 spark plugs

I am about to start getting ready to race currently running E85. The motor is a 12.6 to 1 383 sbc with Dart pro 1 heads I have NGK R5672A plugs in the motor now should I try a different heat range? I would like to see if I have a little more power left in the motor I think I do. Going to do a header change soon but that will wait a couple months. The carb is a 850 Holley converted to E85 by quick fuel. Just thinking of trying a few things different since I will be able to race more than a couple times this year. The car is a footbrake bracket 1/8 mi car.
