ok, im trying to learn more about cams and the heads. 918's are the springs right? so is this a common spring gm uses in other vehicles......just wondering why so many people use them and suggest them. any help is greatly appreciated. and if you want to volunteer any additional info that is greatly appreciated too. thanks

 

918's are a durable spring that Comp Cams has. They fit in place of the stock springs and are good up to .600 lift I think.

 

cool, thanks flyer i can always count on you for a response.
