Are we talking the bolt or the threads in the aluminum? I am sure the threads in the aluminum will give out before the bolt will break. Also, are both heads the same thickness? If the new head is thicker, longer bolts will be needed. A short bolt ( only a few threads in the aluminum) will surely pull a few threads out.
