The best way i have found to see which plug works the best is to just bench test both of them and see what works better.Thats the only way i could tell which would be thte best but,thats just me.You might also try to look and see if they have a spec on diff plugs for that motor.I dont know a whole lot about the brison but, with thte os i have tested all kind of plugs to see what worked the best for my motor.
