AE isn't, but Gregtech is. RP2 has the same thing. You've got to pump A into the Top, B into the bottom and pull out of the side. Try it with the IndBlast Furnace for example. Refined Iron in the top and coal dust in the bottom.
If all else fails, look up GT sidedness, and one of them will be an auto-export side, which will dump into an inventory, including ME interfaces.
On the other hand, you could just set the Import to be Precise and take out only plates, then it will ignore ingots.
