Thanks for the info, as far as I know they are stock 6.0 heads I don't think there has been any porting done to them. I guess I can't complain too much for what I paid. I guess I never thought too much about the cam vs weight thing, but you may be right, I'm not looking to stick a bunch into the motor but would be open to suggestions, I am doing this build with the intent of having a bad ass motor that still gets somewhat dec mileage because I drive it long distances to attend truck shows and have ZERO intrest in building a trailer queen. But like I said if something will work out better I am def open to suggestions. Thanks guys
