Aluminum heads or steal heads

alright guys, im getting the motor together for the camaro. Its going to be a big big block LOL and i cant figure if i want to get aluminum heads or keep my steal heads. What do you all think and what is the benifit of aluminum head vrs steal/.

If i had the extra money for aluminum, I would definitely do it. They are lighter and stronger which is good in my book. Is that big big block a 572 by any chance?? I read somewhere that GM doesn't produce those anymore.

yeah its going to be a big one. Lot of power and torque. Well actually to much power and torque. LOL
