Meh, The Internet can just be a scaremonger to be fair.
You don't know the extent of the problem until you at least strip the head. If you're going to scrap the car/engine, then taking the engine apart wouldn't hurt to just flesh out your options. Ultimately, the head is designed to warp. It's designed to warp as to not damage the block. My friend drove his Mitsubushi Evolution like this and he needed a new head, since I'm told they cannot be skimmed, but the block was fine.
