Using a left hand drill bit to remove a buggered screw

My first attempt at this method. I have not done this before and have had pretty rotten luck using "easy outs". Those often snap off leaving me with a tougher problem than the original messed up screw. 

So I have a 1968 DT1 engine. There was water in the mag cover that corroded the screw heads significantly. So, lets try the left hand drill instead.
