I believe you, top swaps arent cheap. I think they are just getting at the point that the cam is much cheaper to install while you have the engine tore apart already. I had my heads and valves redone for <$40, and it still cost me a grand and a half, with cheap headers. Personally my next step is E85, I've heard good things. All I need is a wideband (which i need anyway) and some injectors. Oh and a pulleyyoull be happy with the top swap for sure, but not quite as happy as you could be lol.
