Hey, I need some advice here and maybe some help. My cousin and I are going to be working on his '98 GSR sometime in the near future when he gets his Skunk2 Cams and Valve Springs, and Spoon 2-piece head gasket. We were figuring that since we will have to take the head off, why not port and polish it. We are thinking on doing it by hand, so I'd like to know what are the pros and cons to doing this. Obviously, you save a grip of money, but what are the dangers? And also, if you know of any good "do-it-yourself" sites that could aid us, please post a link. I would greatly appreciate all the help and info you guys can give us.
