Any of these three packages will outflow stock LT4 heads, and the top end will put you at 500flywheelHP before the blower.

Note that each package indicates the supporting modifications you will have to make, to reach that HP goal.

If you are planning a 700 flywheelHP blower motor, you will need to start from the bottom end up, with a complete, high quality forged bottom end - crank, rods and pistons, plus a 4-bolt main conversion.
