Large valving isn't required on a turbo engine unless you:
a) plan on running really high boost levels
and
b) plan to be on the boost a LOT
Big valves kills bottom-end torque and the turbo will be more than capable of producing over 150 HP using stock valve sizes. The only downside is the extra heat produced by forcing all that air/fuel charge through the stock valves at high boost (an intercooler will help quite a bit).
