i am assembling a customers basket case '36 ford truck that had this rebuilt 289 with it. i was getting ready to bench run the motor and wanted to make sure the valves were adjusted correctly when i noticed the rockers hanging off the tip of the valve. Now by the stick out of the valve past the keeper i would assume a rail style rocker would be needed in this application? does anyone know what part is wrong in this combo here? do the rail rocker measure different than the conventional? the heads seem to have the tight clearance holes for the pushrods so no guides should be needed..

any input would be appreciated.
