need answer ASAP!

I don't have aluminum heads on my car but I don't see no reason why you cant....Aluminum is a very good conductor of electricity.....I think it is 4th on the list of best conductors.....Silver being best, then copper, then gold, then aluminum....Now this is conductor wise I am talking about.......corrosive wise is another order.....also price dictates why we use copper over gold & silver......But your bigger gauge wires like the ones coming into your house panel are usually aluminum....
