was going to breakdown and spend some good cash on new heads for my car, i have forged internals but will i need to put a more aggressive cam in the car too? what horsepower can i expect with the addition of good heads and headers alone. and how much will a cam add to the mix. i would rather not shoot the juice and just have mid to high 500 ponies at the wheels all the time. a blower is in my future but not sure when, i know the heads and cam are a consideration in determining whether a blower is going to be used but are there any heads out there that will work wonders on an na car and just as good if not better on a blown car.
