Man last friday I changed the valvesprings in my GN and what a difference! my car has 95k on the clock and by just doing that It run alot harder in the top of the RPM scale. I figured it would be a little better but, not like that. If your GN or any other performance car has the factory valvesprings in it I would reccomend taking a look at them. I am totally impressed

What method did you use to keep the valves in place? Rope?

nope I used air, and I made my own compressor tool out of an old rocker arm and a metal tube. I was going to pay money for the prefab tool but took a look at it and noticed it was just a rocker arm with a bolt and nut welded on it

What springs did you put in?
