When changing cams or making other valvetrain upgrades to a Ford 4.6L or 5.4L 2V engine, it's important to replace the stock valve springs with a set designed to handle the increased valve lift. Trick Flow® valve spring upgrade kits feature a beehive spring design so they can be installed without machine work to the heads. Both kits come with springs, chromoly retainers, locks, seals, and instructions.
