Rocker problem. HELP!!

First question is what type of valve train are you running,stock or roller rockers.Are the rocker shafts on the correct sides?The stock oiling system runs through the rocker shaft,on the old small blcoks.And if they are on wrong you get very little to no oiling to the rockers.he magnum system uses oil through the push rods to each rocker.You have to have the lifters and push rods to supply oil to the rockers.I would take out the lifter and push rod to check each one and see if the rockers is pumping up.Even get a drill and remove the distributor and prime the motor with a oil pump drive and see if oil is coming out of the lifter and coming through the push rod,and blow out the push rod to see if its blocked,Mrmoaprtech
