I haven't bought and used a set of those heads yet on my bracket E85 S/P car yet but if they take a 3/4 inch reach plugs like SB and 426 hemi use try a Autolite #3933 or the next hotter 3934. I have ran these plugs in both of my bracket motors with aluminum Eddy Victor M.W. on the old motor and with the Indy 440-1 at 15.0 to 1 compression on the new 400 block stroker motor IHTHs

I use the NGK 7 non projected tip with the 240 heads on E85. 440 with 13.2 Ross dome pistons, stock stroke.
It's a Mark Sullens Dominator.

My first E85 motor (14.5 to 1 comp) did NOT like cold plugs, I was running the retracted gap Autolite race plugs, 3932 slow the car down compared to the 3933 and 3934, 3932 being colder The new motor is close to 15.0 to 1 on all eight cylinders and I'm going to be doing more tuning and learning on it this year, if we ever get to race like normal

I'll be doing the E85 change soon. Running 440-1s on a 540 @ 13.5:1. I like NGKs, and it was suggested that I start with the -9 heat range plugs. The NGK -9 plugs are very cold for normally aspirated engines. I suggest starting with -8 for 13.5 CR. The -7 might even be fine for longer plug life.

No I have ran my 800 HP bracket motor on E85 since 2013, it does not like cold plugs at all I would start with a retracted gap NGK-6 (sorry for not knowing that part # ) and then maybe try a -7 later to see what your motor likes. I use Autolite race plugs, part # 3934 3/4 inch reach, 5/8 plug size with a retracted gap
