Just making oval hole bigger is easy, but port-matching the injector notch isn't.

Take a look:

After doing my own research I would like to post my data since it differs from the bee['s pic. Whoever did the above marker work was a bit sloppy in how they represented the FI notch. I also have a view looking right up the intake port in the direction of the injector spray direction to show how little material actually needs to be removed from the notch, which isn't much.
