Good suggestion RooDog! I also think If I take all the inserts out, I may be able to confirm the rollers are installed correctly looking down inside without removing the tappet blocks. It sure acts like I installed them wrong Mike. I have time this week. Taking the wife to the Airport soon for a week in Southern California. Am I correct that the oil drains from the head down through the cylinders and NOT down the pushrod tubes on a 58? My service manual starts from roller motors through shovels.It's a bit confusing.

The HARLEY service mans show the oil returns down the drain holes in the cylinders. But also some splash flows down the pushrod tubes too, and if you look in the lifter blocks you should see a small hole, about 1/8", to vent this drainage. The negative pressure pulses in the crankcase as the pistons ascend and the breather valve closes draws the rocker/valve chamber oil down those channels in the cylinder to the bottom end, then as the pistons descend and the breather opens the oil in the CC is blown into the cam/gear case side of the engine. But we are only concerned here with pressurized oil feed to the lifters.
