You do need to adjust the valves and retorque the heads as Jason said.

You lapped the heads to the barrels or used the sealing rings?
Did you stagger the rings?
Did you check the ring clearance in the lands?
How was the cross hatching on the cylinder walls? did you hone the barrels while you had it apart?
What cylinders are you using with the 96mm pistons?
What was the compression like before? were they all fairly close but then #3 was lower?
