Quiet your engine by tightening the rocker arm to cylinder head end play clearance
Feuling recommends an ideal side clearance of 0.035” - 0.005” for optimum rocker arm oil psi and noise reduction
M8 cylinder heads also have excessive wear on the rocker arm standoff trusting surfaces, when the hardened shim is placed on the thrusting side it will assist in reduction with further wear and damage to cylinder head
Includes six 0.003" thick shims, six 0.005" thick shims and six 0.0010" thick shims
Made in the U.S.A.
These shims should be installed by a professional, one who can make correct end play measurements and can install and tighten rocker shaft nuts/bolts without damaging shims.
