What happened was when I tightened up the pan bolts the paper gasket split in half and the inner half of the gasket dropped into the pan. Luckily I immediately noticed the drop in oil pressure (because of the horrendous valve train noise) and shut the engine down before any real damage was done. Lesson learned, don’t use a cheap pan gasket, and don’t over tighten the bolts. In the photo below you can see part of the gasket is missing on the drivers side front of the pan.
