I am looking into changing the spark plugs on my car since i will be bring it to the dyno on Sat. I am currently running the accel 414s plugs and am wondering if there is a better choice.my combo is a 383 with brodix ik200 64cc heads and 11.1 compression.just wondering what the best plugs are.I also have headers if that matters for clearance.also what gap should i use.i do have a msd 6al box.thanks for the help matt
