What are you hoping to accomplish? The parts combo you are considering ought to make a little over 400 hp, the majority of the power enhancement coming from the headers and the camshaft. If that's all the power you were hoping for then you certainly don't need aluminum heads and in fact prepped OEM heads would be a wiser choice and possibly offer up more horsepower.

I would not run pro comp heads they are not built well I prefer oem heads like dove c or d8ve they will last a lot longer and give you more power then pro comp heads I have not had any good luck with pro comp parts
