![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
Hey!
I dont own a LS1 or a LS6, but a L67 (blown grand prix). I'm looking to do rockers on my heads and had a few questions about the LS6 / LS1 Springs since they happen to be a perfect match for my L67.
GM Part # 12586484
That is a LS6 Spring with 90lbs at 1.8" install height. Coil bind height is 1.190" and outside diameter is 1.290"/1.060" and inside diameter is .885"/.656" And the spring is in a beehive shape correct?
What are the differnces between a factory LS1 and a factory LS6 spring? Differnt material it is made out of ? But are the diameters of the LS1 and LS6 valve spring the same?
Will Crane Cams Retainers (#144832) work with factory LS1/LS6 GM springs?
Thanks for all the help!
