Has any had any experience doing a port and polish to the 8v 2.5L? Maybe even just the polish? I'm a bit low on funds and just looking for something to work on. I read a couple of articles about people just doing some minor polishing (i.e. taking out rough spots and sanding down casting lines) to the intake and it seemed like something I could might be interested in doing. If anybody has any advice concerning this issue or can point me to the right direction I would appreciate it.
