Default 04 STi Steering wheel shake and excessive pulling

04 STi with 133k on it and the front suspension has probably never been touched aside from coilovers. I just got it back from having the heads rebuilt and a new clutch put in. The other night I noticed that maybe 50% of the time when I turn left or right the steering gets a nasty little shake to it. I've also noticed that at WOT the car pulls to the left and when I let off coasts back to the right. Nothing shakes or acts weird driving straight or braking. Any ideas?

Bad alignment would cause the steering wheel to shake!?

Bad alignment would cause the car to thrust to one side under accel, and back to the other during decel. And yes, it could be responsible for the shaking. But I'm going to digress a bit here, and try to undo my lazy first response.

If this all occurred after the clutch was done, I'd be inclined to suspect that the person who worked on the car, unbolted some part of the suspension (including the brakes) to get the axles out of the way so the transmission could be pulled. There's more than one way to do this, so only that individual knows exactly what was done. That said, whatever may have been removed to swing the hub out, would also dictate that an alignment be done after it's all put back together.

The shaking should be reported to the mechanic. It could be that something wasn't seated right or tightened all the way. They should be willing to look at it to see if they've overlooked something.
