In your opinion would it be better to go with Iron heads or aluminum. The iron heads will be the summit brand 152123 $585.00 a set, or go with the aluminum ones on e bay, link below. Remember this is going into a truck at 5000 feet elevation. Also I don't have the confident in myself or enough engine building experience to make this decision without input from people that have been there.
