PURCHASER TO RECEIVE: GMPP LS/LSX SPRING KIT: SPRINGS, RETAINERS, LOCKS, SEALS/SEATS TAKEN OFF BRAND NEW GMPP CNC PORTED LS3 RACE HEADS SO WE CAN INSTALL LARGER VALVE SPRING FOR. This spring kit is designed to be installed at 1.780-1.820 installed height. Coil bind is 1.180-1.200. I recommend install height of 1.810-1.820 for. However, you could likely get by with.
570 lift at 1.800. MORE INFORMATION: One set of GM Performance beehive valve springs taken off of GM's LS3 CNC ported race heads. 550.570 lift before coil bind depending on installed height and will work with just about any hydraulic roller camshaft. The retainers are made from very high quality steel, you can tell by their color and are lightweight, and come with keeper locks, and seals with built in spring locators.They are new 1st quality take offs from brand new LS3 race heads--never used! The retainers are for an 8mm valves --they would fit any LS head or some of the high 23 degree old style Chevrolet heads like the AFR Comp heads with 8mm valve. The Felpro valve stem seal and locators are one-piece together making for a much better set-up than the Lunati or Comp Cam seals that do not fit well and separate locators. These seal better and fit the spring and guides better than the aftermarket 2-piece race set-up. The GM race division usually gets it right more than the aftermarket folks!
