That looks like an awesome deal but I've never seen a set of aluminum heads that cheap. They are cheaper than cast iron and that's a red flag.

Besides, people don't realize that the only advantage of an aluminum head is weight. A cast iron head will create slightly more power as it holds more heat in the combustion chamber. You're also alot less likely to damage a cast iron head.
