I fought that problem when I hit the 600hp mark. The solution was a CDI ignition and the right plugs with a 25-27 thousands gap.

The more air/fuel you pack into the cylinder the more resistance there is to driving the spark across the plug gap. Depending on the strength of your coil the gap may need to be as little as 17-19 thousands. I bet you will find that is the source of the problem.
