Available for later Shovelhead, Evolution and Twin Cam 88 engines, Manley Valve & Spring Kits allow the competent engine builder to purchase one kit when servicing the intake and exhaust valves. Each kit is able to service valve lifts of up to .495”, which makes them ideal for a rebuild using stock or mild cams.

All of the components included in each kit require no special machining of the head to complete the installation, which saves time and money when you’re doing head work. Precisions-rolled double-spring valve spring assemblies apply the proper tension against the forged stainless steel valves and the included keys and top collars keep it all in one spot for miles of reliable power.
