truckernix, I did not know that the neoprene seals would not work. The machine shop that did my o/h put them in. I assumed they had done this before as they were well versed in the o/h of older style engines. In fact the owner had special jigs he made 30 years ago to bore out the rod babbet and install half shell bearings in the rods. He also had the tool for aligning the oil pan squirters so that they were squirting on the right spots on the crank. He was pumped up at getting to use them again. I only wish I had researched the installation of the neoprene seal install before I had the engine back from the machine shop. Live and learn.
