Im looking for some opinions on what I should do for cylinder heads. would it be worth it to machine the stockers for better compression and have them ported or should I look for another set? Id really like to have some heads from dart or world products but they are a little out of my price range for the time being. by the way the intake Ill be using is an edelbrock torker and the cam is a lunati voodoo with .489 intake and .504 exhaust lift and this is not my offroad truck, just a street rod so low end power is not the key goal. thanks.
