It continues to set records today. Modern Casting, an Enhanced Block, and Myths About Cast Aluminum Keith Black Racing Engines has completely retooled and now manufactures the only low-pressure
Aluminum expands at nearly twice the rate of cast iron, which creates a mismatch in expansion rates on bimetal engines with aluminum heads and cast iron blocks. While the heads are designed to handle a certain amount of normal expansion, elevated operating temperatures can push a head beyond those design limits, causing the metal to deform.

Depends how much and how often you overheated them, sometimes they warp so ...

GM made the mistake, many years ago, of manufacturing aluminum engines without cylinder liners of steel or iron, and the result was engines that burned oil at a very low odometer mileage. Nowadays, you don't have to worry about that problem. Of course, aluminum engines are more prone to problems if they overheat, but in terms of durability/reliability, the composition of the
Cracked aluminum can be adequately repaired without welding using an epoxy embedded with aluminum. The aluminum particles contained in the epoxy will adhere to the cracked part, creating a permanent bond that will hold up in most situations. To ensure proper adhesion, you need to prepare the surface of the cracked ...
Aluminum. Aluminum is employed as a deoxidizer in steel and is generally used in conjunction with silicon (also a deoxidizer). A deoxidizer removes undesirable oxygen from molten steel. Once removed, the steel is called ‘‘killed.'' Aluminum–silicon deoxidized (killed) steels are known as fine-grain steels.
The modern gas turbine engine will create a low pressure area in front of the engine that will cause any loose object to be drawn into the engine. The exhaust of these engines can propel loose objects great distances with enough force to damage anything that is hit.
