probably will all the bolts. But you know what? I've had a ton of newer cars with aluminum heads on 4 and 6 cylinders and never used anit-seize on the plugs and never had a problem. But I will on these.....

I don't plan on a hundred thousand miles in between spark plug changes LOL.. I pull them out and look at them too often to worry about them seizing...
