But the bolts will stretch to accomodate the growing aluminum and if designed properly, the bolts will stay in their elastic region. If you think that the force applied by the bolts will overcome the force applied by the heat expansion of the aluminum, then I would suggest an experiment with an iron V8 engine block in the winter time. Let the anti freeze out of your cooling system and fill it with water instead. See what happens in a hard freeze.
No, but the increased force applied by the bolts can cause issues with cylinder deformation....
