Edelbrck vs Trick Flow

So I had speedmaster heads and also switched to trick-flows.

11.35 down to 10.96...... almost 4 full tenths.
What were the speeds with both heads?
Were the SM heads the non-cnc version?
If so, was any porting done?
Same cam/intake/carb with both heads?

What gears/converter/rear tires are you running?
