Need help with 383 setup

Well, First the car is going to weigh more than 2800lbs., and the heads sould be swapped for something newer, 906,452.346s, the ports are just too small for the engine. Yes they did come with them but they are too small for any performance appilcation. Your better off with the newer heads stated. Port volume and flow wise.
What cam centerline is the cam that you have? Then what piston are you planning on useing?
