Manley Performance Valve Springs, LS1/LT1/LT4/L98, 1.290 diameter, Double spring w/o damper, max lift .650"

 

No they are rated at .600 lift. I'll get the specs off the box, but it comes out to .600 lift. I bought these from MTI. The part numbers are off their site.

 

These springs are under "springs" #2 spring in the cam guide section:
