i've seen where it's possible to swap these heads onto a 3.4, and i believe i've seen that the ports are slightly larger, and that theyre aluminum. my motor has 200,000 miles on it and i wanna swap the heads because i believe theres a crack somewhere. would the pontiac heads yield much of a difference as far as power/economy?

Re: Grand Am 3400 heads....
yes they will give you more power, but you have to keep in mind here, its not just the heads you have to swap, you'll need the 3400 pistons and intakes. its not a direct swap lie you're thinking.
theres probabably some things ive missed but thats the jist of it.
