When I made the solid tool post riser on my PM-1440gt I turned the top and bottom using the 4-jaw chuck. With careful measuring and adjusting I was able to get the top/bottom within .0002" this way.
I agree with Dabbler on using a single long T-nut on both sides with 2 screws each. If you feel the need to key it, I would slot the bottom of the riser block and then make the T-nuts taller to also act as a key.
How wide is the QCTP? 2" seems kind of narrow for a riser block.
