In terms of FB385 vs. 383, a 383 will make a little more power (20 to 30 HP) and they have a flatter torque curve.

Id also point out that with current after market components, the 383-406 can make exceptional power.

The Brodix 227 head is probably going to make about the same power as the AFR 220 head. Instead of changing heads, I'd spend the money on a better carb and a better ignition system.
