I'm currently undecided between buying new LS rocker arms (around 300 bucks or so) or just getting my current ones resurfaced. The guy who sold me the head had removed them and not labelled them, so I can't be sure which goes where. I'll be using RM regrinds for the rebuild, so will it even matter where they go? I know wear is a factor, but with a new cam profile is it THAT important? what are some educated recommendations on resurfacing?
