Jeff,

Davids numbers are right on the money. With some work you CAN get to 300-400PPM HC. When you do I think your flat spot will be gone. Anything over about 1000-1200ppm HC indicates a dead miss. At 300-400 (on a carbed car & below 200ppm on injected) indicates a nice degree of cylinder firing efficiency across the entire bank.
