Out With the Hydraulic Roller and In With A Solid Roller

hollow B&B pushrods aka Magnum, your size may vary. Most hydro flat tapped lifters have the oil hole in them anyway to satisfy AMC applications. Im sure the 843-16's have the oil hole in the seat. I see no reason why you would not want to run hollows if you had the oil hole and the rockers did not have an oil jet. Oil is good.
