Thanks for all of the advice. My son and I removed the front rocker shaft and replaced the oiler. There was enough line to make a connection above the head. Started the motor to check if everything worked and after a bit there was oil coming out of the holes in the top of the rockers. Could also see oil going back down the return.
Since the cover was off we let to car run to get the oil to temp to check and adjust the valves. Took a bit to do. Prior to the adjustment the valves were quieter but the engine did not seem to start or idle as well. It ticks now like a watch. We did find several of the valves needed to be tightened.
Did not get the valve cover back on yet. Spent the rest of the night looking at how things work. My oldest was interested in how the cap and rotor worked so we looked at it. Also watched how the rods moved the rockers etc. First time he saw the head open while running. Plan to double check everything and get the cover on next chance we get.
