It may take a while for the smoking to stop. I changed mine then after a month it slowed down. You may have a lot of oil and crud sitting on the back of the valves and it will take a while for the gas to wash it off.
I only drive less than a half mile to my work so when the smoking did not stop over the next few days I got pissed.
Do you let it high idle in the mornings while it warms up, mine will smoke if it does and if I rev the motor heavy while it's cold.
