Bob received the custom made replacement piston rings to fit the new pistons and oversized bores. Also had a set of 8 soft copper gaskets made on a CNC laser cutter by an outfit in Kentucky. Cylinders are just about ready to be mated to the block. Then the pistons can go in. Still have some work to do on the packing gland assemblies. The valve glands are nearly ready. Piston glands still need final cleanup. All the cylinder studs were cleaned up and chased. Cylinder threads were all chased. New nuts for all the studs. Nuts are stainless steel.
