I prefer manifolds for ease (or lack of) maintenance vs headers. I have run both over the years an only really noticed the difference in power on a 383 in my 79 Malibu, but it had the "log" manifolds originally. They were ceramic coated and the coating did seem to help lower the underhood temps. Between that and having a cowl induction hood not sealed to the carb, (never got around to it) you could work on the engine and not get burnt after letting it sit for just a few minutes after shutting it off. I have heard, and would agree that the ram horns on our trucks flow better than the later "logs".
