Installation tip: For 850 Eldorado, it is important to verify that the push rods do not contact the cylinder or the cylinder head or the head gasket prior to final installation. Loosely assemble all components and rotate the engine through 4 strokes several times while inspecting each push rod through all 4 strokes using a flashlight to visually inspect. Depending on the combination of cylinder heads and rocker arms, some combinations are more likely to require additional clearance than others. Increased clearance is quickly and easily obtained by use of a rat tail file.
