Hi I have 1995 Mustang Gt so I should still have the E7 Heads if i am correct. I am thinking about upgrading to GT40 heads I am not sure if anyone has a better idea for me. I have a e303 cam, edelbrock upper and lower intake, 75mm throttle body still running the 19lb injectors I haven't felt the need to swap from them yet. My whole thought on going to gt40 heads is I could get them then swap to 24lb injectors and get a cobra tune/maybe with a diablo tune. What are your suggestions?
