Be careful of adding too many spacers. I saw evidence of the adjusting screws hitting the valve cover. I since have shortened my push rods and removed spacers. It is not difficult to shorten push rods. The nipple end is very hard and you can't damage it. I chuck the nipple in my drill press just above the top edge of the tube, with the bottom end in a hole in a hard board. You can use a hack saw blade or the edge of a small thin file to remove the metal just below the nipple. Some of the saber saw blades are different thicknesses. When you break through the tube you won't even scratch the nipple. Then drive the nipple back down in the tube. It takes about an hour to do four push rods. Removing .020 to .030 of tube length is worth one of two shims.
