I know two people that have the power heads.Both say that for the money,you can't beat them.They are great for a mildly worked over motor and make tons of torque alsne is in a Fox body and the other is in a 65 Falcon.Both are automatic cars.Aluminum heads are good,but for down right longevity I'll take cast iron.Especially on a street car.Also,if you call them,they are real friendly people who will answer all your questions.
