I wouldn't change the rotation of the body your self. Your initial approach 
look fine to me. Make sure that 'y' is really the top of the piece. Try it 
with a value of 0. If y is correct then there could be a problem with the 
friction. I assume that the piece rests on some ground plane or a box geom. 
Check the contact points that are created for the piece and the ground.
