The big benefits of aluminum are lighter weight and the ability to run higher compression. The downsides are corrosion from dissimilar metals and less durability under detonation. There are some manufacturers offering iron and aluminum heads that are identical except for the materail, so it's not necessary to to buy aluminum to get performance. I selsected iron heads for my 351 because it is a truck motor, saving a little weight on the motor really doesn't mater, and the iron heads were $250 cheaper than the aluminim versions.
