These genuine GM 602 valve springs are hand-picked and tested. Keepers are included as it is recommended they be changed each time valve springs are replaced. Our intake springs (red tie) meet the high-end specs; our exhaust springs (black tie) are in the mid-range specs as they are less critical and will save you money.
Also included is our "original" instruction sheet on valve adjustment.
