I guess its good that I don't hold any special love for my 305 then.

With pre-ignition the second flame front doesn't happen in sync with the one started from the spark plug. This is two at the same time, or, one with a jet coming off. This fast burning uses more energy and less heat, so it can get rid of detonation. Theoretically.

You want the flame to travel through the whole chamber and "swirl" when the plug goes off, thats why swirl port heads make great down low response. They stink because they have obstructions in the intake path that screw up all the mid-range to high-range airflow. A modded combustion chamber can do the same thing without putting crap in the intake path.

I can only think why this would work great and look at others results. The proof will be in the pudding sometime this summer if tuition isn't going to kill me.
