What heads and Intake manifold did you guys choose? Whats a good one to go with if you plan on going turbo later on? I want to give my 5.0 a little bit more of a kick until I can buy my tubro kit. I know more air = More Power. What Head-Intake manifold combo would you go with and if you got a good site with a good price, please throw it at me. I'm currently looking at http://store.summitracing.com/egnse...4839079+115&Ntt=&Ntk=&rsview=sku&RC=100#rstop If you had to choose from that site which would you choose?
