[QUOTE]Originally posted by Adam5.0: [QB] [QUOTE]Originally posted by 84SVOrick: [qb] Cast iron heads are stRonger but heavier. Actually fuel atomizes better with irons. If you own a heavier car your gonna need the weight loss. [/qb][/QUOTE]Wrong and wrong. Cast iron heads are pretty much ancient history. Its hard to find them used on any cars made in the last 5 years or so. So basically we have established that with port work they can flow just as well as aluminum. but if we port some aluminum. heads the gt40 are still beat. weight is everything in the speed game. aluminum heads weight 50lbs less and everything counts. you can have a 1000 hp engine in a tank, that doesnt mean it will be fast. I still think there is no question on which one is better. no one said you cant make power with gt40's but you have alot more potential with Aluminum stuff. [/QB][/QUOTE]
