I have everything for a top swap and PEMS but I want to be safe and go with the standard pulley and headers. This is my daily driver and I drive more than 400 miles per week often more far from home. Is there a set of headers that will last for the life of the car and not leak? I don't want to be gooping RTV every six months and worrying about something cracking. It seems like every thread on headers involves RTV parties, I have the original short block and maybe I'll just freshen it up and use it with the PEMS. Thanks in advance.
