if you do it right, maybe 5-10, if you do it wrong, you will just make it worse.
I would personally not waist the time, it would take to do it.
THe time involved in pulling the heads, and doing the work, and the cost of the supplies, and the posibilty of messing up one of the heads.
For the time and money invested, it just really isnt worth it to me. If you want to save some money, and want more flow, go pick up some used gt-40's.
