Abstract
A valve train module which can be assembled, tested, shipped and then mounted to the cylinder head of an engine and actuated by a camshaft to effect operation of the intake and exhaust valves for the respective associate cylinders formed in part by the cylinder head includes a rocker positioner used with flanged hex head bolts to support and retain a pair of rocker shafts in a predetermined spaced apart parallel relationship to each other, with each such rocker shaft pivotably supporting associate rocker arm assemblies that are maintained in axial spaced apart relationship to each other by rocker arm positioners on the rocker positioner.
