I need a budget set of heads and am wondering whether or not to just port my E7 heads or maybe look into the GT40P heads. Why are the GT40P heads so cheap over the other GT40 heads? I don't know too much about heads so any info will be appriciated. My car has a low/mid cam, TrickFlow Trackheat intake, 70mm throttle body, and underdrive pulleys. Also is moving to 24 pound injectors going to be worth doing with my setup, and if so will there be a big gas mileage drop(this is my daily driver) thanks guys for any imput.
