This is in regards to a stock S5 turbo w/ 2 cracks on the hotside.

I've taken the hotside of the turbo apart to port out the wastegate, only to discover it has a few cracks in it. I'm unsure of what is acceptable or not. Below are a few terrible pics from my cell phone, but at least you can see where they are. Should I just forget about the 2 cracks and port this one, or get another hotside?
