Looking for a plug recommendation to establish a baseline on a brand new build..
505ci RB , 11-1 CR
Home ported (by me)Promaxx- (same as Sidewinders) 210 cc heads
Bullet "street"Solid Roller 254/260 @.050 109 lsa
Trick Flow single plane
ATM Innovations 950 cfm E85 carb
4.10 gear S60 , RMVB 727 3500 vert ,28"tire
Car is 3,600 with me in it
95% street driven
I will be running a wideband.

Big question on the plugs.. projected tip ? Non projected ? ... and heat range recommendation. Im a total e85 newb
And this is my first stroker build too. Just wanna start off in the right ballpark plug wise if possible. Thanks for any info.
