I just hit 15K so a major service is in order. I'm gonna do my valves in the next 2 weeks...just waiting on new plugs. I searched and didn't find a HOWTO on doing the valves in Perf and Tech...so I'll do one with pictures. My fingers are crossed that I won't have to pull cams but then again if I do it'll be better for the masses I guess. More to come when I get my new plugs.
