I run into this a lot. The cam mfg says a spring that is way to light according to my engine builder. So there is a tough quandry because you generally like to follow the mfg recomendations...

I always do what the engine builder suggests, which is more spring pressure and have never had a motor fail because of that.

Once again, generally, you won't have a problem if there is too much spring pressure (to a point) vs. too little...



Exactly what these builders said. Hardly ever see a stem pulled away from a valve.
