did 5.3 motors come with aluminum heads? i found a motor that is suppost to be a 5.3 but it has aluminum heads with a iron block. i thought only some 6.0 motors had aluminum heads but i don`t know much about these motors. any help would be great. thanks.

My 99 5.3 has aluminum heads and an iron block. The 6.0 that year had iron block and heads.
